Severe blood loss can cause circulatory shock, depriving the kidneys of oxygen and leading to acute kidney injury or renal failure. If not quickly treated, shock can cause permanent damage or kidney failure. New treatments with mesenchymal stem cells are being studied to reduce kidney damage.

When a person survives a trauma that causes massive blood loss, their kidneys may suffer damage leading to acute kidney injury or permanent renal failure. This is because the kidneys require a steady flow of blood to filter waste from the body. Massive blood loss can lead to a condition called circulatory shock, a life-threatening situation where the circulatory system fails to supply sufficient oxygen and nutrients to tissues. This lack of perfusion and oxygenation can result in kidney cells being deprived of oxygen (ischemia), leading to cell death and kidney failure. In some cases, if the kidneys are not seriously damaged, they may recover, but often the damage can lead to permanent loss of function.

Following massive blood loss, a patient's body may enter a state of hypovolemic shock. Treatments for hypovolemic shock typically involve intravenous fluids to restore normal function and drugs to raise blood pressure. If circulatory shock is not corrected quickly, it can lead to a positive-feedback loop, resulting in organ failure, including renal failure. Advances in medical research, such as the use of mesenchymal stem cells, have shown promise in reducing the instances of kidney damage after traumatic injuries or surgeries by promoting regeneration and repair.

Answer:

The answer is: horizontal plate of palatine bone and palatine process of the maxilla bone.

Explanation:

The nasal cavity is the bilateral air-filled space present above the roof of the mouth and behind the nose, that forms the interior of the nose.  

The hard palate forms the roof of mouth and floor of the nasal cavity. The bones of the hard palate that are present on the floor of nasal cavity are the horizontal plate of palatine bone and palatine process of the maxilla bone.

The bones that form the floor of the nasal cavity are the palatine processes and the horizontal plates of the maxilla bone. These components of the maxilla bone shape part of the nasal cavity's floor and part of the face's structure.

The bones that form the floor of the nasal cavity are the palatine processes and the horizontal plates of the maxilla bone. The palatine processes of the maxilla make up the anterior three-quarters of the hard palate, and the horizontal plates of the palatine bones make up the posterior one-quarter.

The maxilla bone is one of the most significant facial bones, shaping not only the middle third of the facial structure but also providing the basis for the eye socket and the nasal cavity. The term 'process' in the phrase 'palatine process' refers to the protrusion of a bone. Therefore, the 'palatine process' is a part of the maxilla bone that extends to form a portion of the nasal cavity's floor.

Answer: b. brachialis

Explanation:

The brachialis is the muscle that is present in the upper arm of the flexes of the elbow joint. It lies below biceps brachii. It forms the part of the cubital fossa. It does not cross the elbow joint. It is the prime mover of the flexion of the elbow of the hand.

Final answer:

The supinator does not cross the elbow joint; it is responsible for supination of the forearm. The brachialis, biceps brachii, and triceps brachii all cross the elbow joint and are involved in either flexion or extension of the forearm. The correct answer is a. supinator.

Explanation:

The muscle that does not cross the elbow joint is the supinator. It is solely involved in turning the forearm anteriorly, which is known as supination. The other options, brachialis, biceps brachii, and triceps brachii, all cross the elbow joint.

The brachialis and biceps brachii are responsible for flexing the forearm, while the triceps brachii is the muscle that extends the forearm. Therefore, the correct answer to the question is the supinator, as it does not participate in elbow joint movement like flexion or extension.

Answer: Glycogen

Explanation:

Glycogen is the most efficient form of energy storage. This is because the energy is stored  in the form of glucose can be easily converted into glucose to be used by the body.

Primarily the energy is stored in the form of glycogen only. It is stored in the liver and muscle cell of the body.

The energy required to break the bond of glycogen to convert into glucose is less as compared to other macromolecules.

Hence, the correct answer is option C

Answer:

The correct answer is d) Lipids

Explanation:

Lipids are fat molecule which contains mainly triglyceride made up by the body when extra energy is consumed. Body store lipids to provide energy to the body when there is no glucose left to provide the energy so it acts as a energy reserve.

It is the most efficient form of energy storage because it can provide more calory of energy per gram than protein and carbohydrate.1 gm of lipid can yield 9 kcal while 1 gm of carbohydrate only yields 4 kcal.

So body can go long(weeks) without food due to the energy provided by stored lipids. Glycogen can only provide energy for one or two days.

Answer:

The correct answer to the question: The contraction phase of the cardiac cycle refers to diastole, would be, B: false.

Explanation:

The cardiac cycle is defined as the process by which the heart fills up with both oxygenated and de-oxygenated blood, and pumps one towards the lungs for oxygenation and the other towards the body, to delived oxygen and other nutrients to the organs. In order to accomplish this function, the heart has two parts in its cycle, the sistole and diastole. The sistole is the part of the cycle when the heart literally squeezes its chambers, both the atria and mostly the ventricles, to pump out the blood present in them. Distole is the part of the cycle when the chambers relax, and open to their fullest extent, to permit the entrance of the necessary blood from the vessels, so that a new cycle can begin. This is why the answer would be false. Diastole is when the heart is relaxed and getting filled with blood.

Answer: Trachea

Explanation:

The Eustachian tube is also known as auditory tube which connects the nasopharynx to the middle ear. It is a part of middle ear.

The fauces is a part of the oropharynx which directly opens in the oral cavity as a sub division. It is superiorly bounded to the soft palate.

Esophagus is a muscular tube which is a connecting link in between pharynx and stomach.

Hence, trachea is not an opening found in the pharynx.

Answer:

TRUE

Explanation:

In the cardiovascular system, the blood flows from high pressure to low pressure.

In the ventricular ejection phase, when the muscles of the ventricles contract, the pressure gradient in ventricles rises. This increases in the pressure in the ventricles exceeds the pressure in the pulmonary artery and aorta, thus opening pulmonary and aortic valves and ejecting the blood from the heart.

Answer:

The correct answer will be option-A

Explanation:

Electrocardiogram or ECG is the recording and representation of the electrical changes that are taking place during the cardiac cycle.

The QRS complex is preceded by the P wave or atrial systole or atrial depolarization after which the electrical signals are passed on to the AV node.  

As soon as the AV node passes the electrical signals to bundle of His, it is observed in as the QRS interval which represents the atrial diastole and the onset of ventricular depolarization.

Thus, option-true is the correct answer.

Answer:

C. Prevents the development of female internal reproductive organs in an XY male.

Explanation:

Antimüllerian hormone, also known as Mullerian inhibiting hormone, is a protein responsible for preventing the formation of Müllerian ducts in a male embryo (XY). Müllerian ducts, also known as paramesonephric ducts, are structures that are present in the embryo and give rise to female internal genitals if they are a girl or remain in their vestigial form if they are a boy. This vestigial form, which is formed in boys, is caused by the presence of antimullerian hormone.

Answer: a. lipid-soluble hormones generally have a longer half-life.

Explanation:

The hormones are the chemical substances which are produced by the glands it in the body to conduct a specialized function in the body. The biological half life of the hormone can be define as the time it takes so as to reduce half of it's functional or physiological activity.

The lipid soluble hormone does not easily solubilize in the body fluids. It is easily diffuse through the cell membrane and performs it action. It generally have a longer half life. The examples of the such hormones includes progesterone, testosterone and aldosterone.

Answer:

The answer to the question: Steroid hormones are usually released in large quantities into the blood, would be, B: False.

Explanation:

Essentially, hormonal activity has one purpose, to stimulate and excite the activities of target cells. Steroid hormones produced by the gonads and also the adrenal glands, also have this purpose, to induce target cells to perform a specific function. Because their purpose is excitatory, large amounts of them released into the blood could cause serious stress to the body, and in any case, the body itself has regulatory systems that, once a certain exitatory threshold has been reached, regardless of the amount of new hormones arriving at a cell, this one will not respond, because there will be no further receptors for it. Steroid hormones, thus, are released in small amounts usually, in order to maintain the target cells functioning as they should. Large amounts will NOT be USUALLY released into the bloodstream, unless there is a situation that merits this burst in them. But normally, steroid hormones are not released in large quantities into the bloodstream.

Explanation:

Aldosterone is steroidal hormone which is produced by outer-section of adrenal cortex in adrenal gland. It acts on distal tubules and the collecting ducts of kidney to cause conservation of the sodium by facilitating the secretion of the potassium and increased water retention.

Atrial natriuretic hormones are natriuretic peptide hormone which are secreted from cardiac atria. Main function of the hormone is causing reduction in the volume of the expanded extracellular fluid by increasing the renal sodium excretion.

Thus, Atrial natriuretic hormones causes sodium and the Water loss while Aldosterone helps in the conservation of the sodium and water retention.

Aldosterone and atrial natriuretic hormones (such as ANP) are antagonists because aldosterone promotes the reabsorption of sodium and water, increasing blood pressure, whereas ANP promotes their excretion, reducing blood pressure. ANP inhibits the release of aldosterone, renin, and ADH, ensuring balanced regulation of blood volume and pressure.

In what way are aldosterone and atrial natriuretic hormones antagonists? Aldosterone and atrial natriuretic hormones serve opposite functions in the regulation of blood volume and pressure. Aldosterone promotes the reabsorption of sodium (Na+) and water in the kidneys, an action that increases blood volume and pressure. In contrast, atrial natriuretic hormones, such as atrial natriuretic peptide (ANP), counteract this effect by promoting the excretion of Na+ and water, leading to a decrease in blood volume and pressure. ANP achieves this by inhibiting the release of aldosterone, renin, and ADH (Anti-Diuretic Hormone), effectively reducing Na+ and water reabsorption in the kidneys. This antagonistic relationship between aldosterone and ANP ensures a balanced regulation of blood pressure and volume, responding to physiological needs such as the need to lower blood pressure in conditions like heart failure.

Answer:

The correct answer is D.

Explanation:

Papillary muscles, attached via chordae tendineae, help to close the valves and prevent regurgitation.

Pectinate muscles are parallel ridges in the walls of the atrium of the heart, mainly in right atrium. They can stretch during adverse loading conditions, to help the right atrium to dilate without much wall stress.

The mismatched pair is D. pectinate muscles - muscles that close valves. Pectinate muscles are actually located in the atria of the heart and they don't perform the role of closing heart valves.

The mismatched pair in the options you've provided are D. pectinate muscles - muscles that close valves. Pectinate muscles are actually found in the atria of the heart. They do not close valves, rather they help in the contraction of the atria emptying the heart chambers during a cardiac cycle. Option D is incorrect because pectinate muscles have no role in closing the heart valves which is actually performed by papillary muscles.

Answer:

The correct answer will be- Atrial natriuretic factor (ANF).

Explanation:

The atrium of the heart plays important role in regulating the blood volume and blood pressure.  The mechanical stretching of the atria leads to the release of an important hormone called atrial natriuretic factor.

ANF acts by increasing the excretion of sodium and inhibition of renin in the kidney as well as antagonizing vasoconstriction and shifting the fluid from  intravascular to the interstitial compartment in the cardiovascular system.

Thus, Atrial natriuretic factor is the correct answer.

Answer:

Explanation:

The oral cavity aids in the transport of air when may be obstruction in the nasal cavity.

The Rib cage aids in the movements of respiratory inspiration and expiration  through the intercostal muscles and other estructures.

The Diaphragm aids in the regulation of the respiratory movements and the input and output of air into the lungs.

The Trachea is actually a main passage of air to the bronchi and then to the lungs, so it is not an accessory structure, it is a main structure needed for the process of respiration.

e. Carbohydrates, lipids, proteins, and water

Explanation:

Macronutrients -

It is a chemical substance or element which is required in large amount for the growth and health of the living organism .

The three macronutrients are lipids , carbohydrates and proteins .

The examples of macronutrients are as follows -

Water , proteins , lipids , Carbohydrates , glucose , sucrose , amino acids .

The macronutrients are:  Carbohydrates, lipids, proteins, and water.

The correct answer is option E.

Here's a breakdown of each macronutrient:

Carbohydrates: These are a primary source of energy for the body and include sugars, starches, and dietary fiber. They are found in foods like grains, fruits, vegetables, and legumes.

Lipids (Fats): Lipids are essential for energy storage, cell membrane structure, and the absorption of fat-soluble vitamins. They include fats and oils and are found in foods like avocados, nuts, oils, and fatty fish.

Proteins: Proteins are crucial for building and repairing tissues, enzyme function, and immune system support. They are found in a variety of foods, including meat, poultry, fish, dairy products, legumes, and tofu.

Water: Although not a source of calories, water is considered a macronutrient because it is required in large amounts for various physiological processes in the body. It is essential for hydration, temperature regulation, and the transport of nutrients and waste products.

Nucleic acids (such as DNA and RNA) are not considered macronutrients. They are vital for genetic information and cell function but are not consumed as part of the diet. Sodium, potassium, calcium, chloride, and phosphorous are considered minerals and electrolytes rather than macronutrients, as they are required in smaller quantities compared to macronutrients and have distinct roles in the body.

So, option e is the correct choice for the macronutrients.

To calculate the daily dosage range of chlorothiazide for a 48-lb child, convert the weight to kilograms and use the pediatric dosage recommendation of 10 to 20 mg/kg per day.

To calculate the daily dosage range of an oral suspension containing 250 mg chlorothiazide per 5 mL for a 48-lb child, we need to convert the weight from pounds to kilograms. 48 lbs is equal to 21.8 kilograms.

Now, we can calculate the dosage range using the pediatric dosage recommendation of 10 to 20 mg/kg per day. For a 48-lb child, the dosage range would be:

Therefore, the daily dosage range for the 48-lb child would be 218 mg to 436 mg of chlorothiazide per day.

The daily dosage range of the oral suspension for a 48-lb child is approximately 0.87 mL to 1.5 mL.

To calculate the daily dosage range for a 48-lb child, we first need to convert the weight from pounds to kilograms.

1 lb is approximately 0.453592 kg.

So, 48 lbs is:

48 x 0.453592 ≈ 21.77 kg.

Now, we'll calculate the dosage range based on the pediatric dosage guidelines:

For a child weighing 21.77 kg:

- Minimum dosage: 10 mg/kg/day

- Maximum dosage: 20 mg/kg/day

Let's calculate:

Minimum dosage:

10 mg/kg x 21.77 kg = 217.7 mg/day

Maximum dosage:

20 mg/kg x 21.77 kg = 435.4 mg/day

Since the maximum dosage should not exceed 375 mg/day, we'll consider the maximum dosage as 375 mg/day.

Now, let's calculate the dosage range in terms of mL of the oral suspension:

Given that the oral suspension contains 250 mg of chlorothiazide per 5 mL, we can calculate the dosage range:

Minimum dosage (in mL):

217.7 mg / 250 mg/mL = 0.8708 mL/day

Maximum dosage (in mL):

375 mg / 250 mg/mL = 1.5 mL/day

Answer:

The best answer for the question: These data indicate a defect in which of the following? when talking about a patient who is able to absorb disaccharides, like maltose, fructose and lactose, but not complex polysaccharides, like starch, would be, D: Pancreatic enzyme secretion.

Explanation:

The importance of the pancreas for human nutrition, cannot be stated enough. It is this organ that is responsible for the secretion of the majority of the enzymes responsible for breaking apart the molecular unions of complex nutrients, such as starchs, fats, and proteins, to reduce them to their more basic units, so the body can absorb them and use them. If these pancreatic enzymes are either absent, or faulty, then complex nutrients cannot be broken down, regardless of what other enzymes might be working properly after. If the main chemical bonds of the molecules cannot be undone, then other enzymes cannot do their own work. Panceatic amylase is central for starch break up into smaller mono and disaccharide units, and from there, brush border enzymes in the small intestine take over to further break these into basic units that will be absorbed. In the case of this patient, amylase is probably absent, or is faulty, which is why he cannot absorb glucose from starch, but he can if he eats simpler foods with more basic sugars. This is why the answer is D.

Answer:

The coreect answer is C)  release their secretions directly into body fluids.

Explanation:

Endocrine cells are found in endocrine glands which are also called ductless glands and release their secretions directly into the body fluids. The secretions are mainly hormones and they reach their target organs through blood.

The major endocrine glands are pituitary, thyroid, parathyroid, pancreas, adrenal, ovaries and testicles. Hormones released by these glands regulate the functional activity of their target cells and organs.

Some of the glands like hypothalamus and thymus contain cells which secrete hormones also comes under endocrine system but are not called endocrine gland.

Endocrine cells secrete their products, such as hormones, directly into the bloodstream or surrounding tissues, distinguishing them from exocrine glands that use ducts.

Endocrine cells release their secretions directly into body fluids without the use of ducts, which is a defining characteristic of this type of gland. In contrast, exocrine glands secrete substances through ducts to an epithelial surface or the exterior of the body. Endocrine glands are comprised of epithelial cells that have been modified for their specific secretory function, secreting hormones into the interstitial fluid and bloodstream, influencing various physiological processes. Endocrine secretions include hormones, which regulate many bodily functions and processes.

Answer and explain:

Bronchial arteries are provenient of thoracic aorta. Their origin is in systemic circulation and their function is provide oxygen blood to big vessels, visceral pleura and walls and glands of bronquios. Also, bronchial arteries are encharged of humidify the air to reduce it loses by evaporation in alveolar surface.

Bronchial arteries are components of systemic circulation.  

Bronchial arteries give the nutritional circulation to the non-respiratory structures in the lungs. The left bronchial arteries are usually 2, they directly emerge from the thoracic aorta, while the right bronchial artery emerges from the third intercostal artery or from the left superior bronchial arteries. That the bronchial arteries emerge from aorta explains how they made a part of systemic circulation.

Before these arteries penetrate the lungs, they also give some branches to pericardium, lymphatic ganglia’s, esophagi and bronchioles. This circulation is characterized for having a high pressure but a low flux. The pressure that these arteries manage has no significant differences whit the aortic pressure. 

Answer:

The blister formation process is an excellent illustration of the connection between the structure and function of the skin because it covers the tissue below, protects it from further harm and allows it to cure.

Fluid collects from the upper layers of the skin (the epidermis) to the lower layers (the dermis).

Final answer:

Blister formation showcases the relationship between the skin's structure and function by demonstrating its protective role and adaptability. The epidermis and dermis work together when forming blisters to cushion and protect deeper layers, reflecting the skin's role as an organ of adaptation and its functions in homeostasis and thermoregulation.

Explanation:

The process of blister formation is a clear example of the intricate relationship between the skin's structure and function. Blisters are raised areas on the skin filled with fluid, and they form as a result of the skin protecting itself from damage. The outermost layer of the skin, the epidermis, acts as a barrier, while the layer beneath it, the dermis, provides support and flexibility and houses blood vessels, nerves, and other structures important for the skin's functions.

When the epidermis is damaged due to friction or other causes, the body's inflammatory response leads to the formation of a blister. This space fills with fluid to cushion the tissue underneath, protecting it from further injury and allowing it time to heal. Therefore, blister formation highlights the skin's role as an organ of adaptation and its ability to respond to environmental challenges by protecting the rest of the body.

Moreover, the skin's function in thermoregulation is closely tied to its structure. Variations in blood flow through the skin help to maintain body temperature, demonstrating how the structural components of the skin such as blood vessels play a pivotal role in its function of homeostasis.

Generally it helps in producing the secondary, tertiary and other s immune responses for the same antigen. It is observed in helper T cells but also by the B cells.

Answer:

The correct option is: B) peristalsis

Explanation:

Peristalsis is the involuntary wave-like contractions and relaxations of the smooth muscles of the gastrointestinal tract of the humans.

These alternating contractions and relaxations produces a peristaltic wave that pushes the food down the esophagus of the digestive system. The peristaltic movement prevents the food from moving backwards and pushes the food forward.

The appropriate term for the waves of muscular contractions that help move the content in the digestive tract is peristalsis. It is part of the digestive process and is not to be confused with other processes like mastication or segmentation.

The waves of muscular contractions that propel the contents of the digestive tract are referred to as peristalsis. This is a crucial process in the digestive system as it allows for the movement of digested food substances from one point to another. It can be differentiated from the other options because while mastication refers to the act of chewing, pendular movements pertain to a type of mixing wave in the small intestine, segmentation refers to the back-and-forth motion in the intestines that breaks down food, and churning movements refer to the stomach's process of mechanically breaking down food.
