Free Radicals in the Body

Free radicals are unstable molecules that can damage the cells in your organism. They result when atoms or molecules gain or lose electrons. They  are byproducts of ongoing metabolic processes.

Antioxidants are those molecules in cells that prevent loose radicals from taking electrons and causing celldamage. Antioxidants are capable to give an electron to a free radical without becoming destabilized themselves, thus hinder the free radical chain reactions

Nutrients that act as antioxidant

  Most cereals. vegetables and fruit every day. fish, coffe, strawberries or any kind of berries,etc.

Answer:

We talk about organic foods to all those products, whether vegetable or animal that come from a breeding or cultivation where no type of chemicals or hormones have been used for their development, nor have they undergone forced or artificial processes.

These foods have the following benefits:

- freshness

- nutritional value

- they're healthy

- they are not polluting for the environment

Answer:

The correct answer will be option D.

Explanation:

Excitation–contraction coupling is a link process which converts the electrical impulse to a mechanical response. It links the action potential of the sarcolemma to the muscle contraction.

In this process, when acetylcholine binds to the receptors it leads to the generation of the action potential. This action potential travels down via T-tubules from the sarcolemma to sarcoplasmic reticulum due to which calcium ions are released into the sarcoplasm. These calcium ions bind to the troponin which leads to the binding of the myosin to actin forming cross-bridge. This cross-bridge pulls the actin causing muscle contraction. This impulse generation and muscle contraction repeat again.

Thus, option D is the correct answer.

The coupling of muscle excitation and contraction is best described by calcium channels being stimulated by depolarizing T-Tubules, which then open and release calcium ions into the sarcoplasm. This leads to the initiation of muscle contraction.

The process you're referring to, which involves the coupling of muscle excitation and muscle contraction, is best described by option C: Ca2+ channels, stimulated by depolarizing T-Tubules, open and release Ca2+ ions to the sarcoplasm. This is an integral part of the excitation-contraction coupling mechanism which happens within muscle cells during contraction.

In this process, an action potential travels along the sarcolemma (the muscle cell membrane), and into the T-tubules, which are essentially inward extensions of the sarcolemma. The depolarization of the T-tubules causes the adjacent calcium channels in the sarcoplasmic reticulum membrane to open and release calcium ions into the sarcoplasm, where they then interact with contractile proteins to initiate muscle contraction.

Answer: Option d

Explanation:

In case of Cesarean section, large bleeders are clamped and not ligated because there is a chance of postpartum hemorrhage which is very fatal for the mothers.

It has been recorded that almost 1 to 5% of the women die after giving birth to the baby because of excessive blood loss.

So, it is better to clamp the placenta rather than to ligate it as it would not prevent blood loss.

Answer:

The answer to the question: All EKG leads monitor the same electrical events but do so from different perspectives, is, true.

Explanation:

The EKG is a diagnostic test whose purpose is literally to observe the electrical current that circulates the myocardial muscle as the heart begins to move to pump blood towards the body and towards the lungs for oxygenation. The EKG is a machine, with electrodes, that are capable of tracing the pattern, direction, and strength, of these electrical currents as the heart muscle depolarizes and repolarizes during a cycle. This means that all the leads in the EKG perform the same task, to measure the electrical current, but they do so from different directions, to measure how the current activates and stimulates the contraction and relaxation of the different parts of the heart. The positions of the leads, will depend on what part of the heart, during a cycle, wants to be observed electrically. Usually, the most common EKG asked for by doctors is the 12-lead EKG, which literally monitors all surfaces of the heart involved with this electrical current.

   Tissue Membranes

       Connective Tissue Membranes

       Epithelial Membranes

Explanation:

Tissue membranes are thin layers of cells that are covering the outside of our bodies, (ex; skin, ) organs ,  or like smotach they are internal passages that continue opening to the exterior of our bodies.

The mucosa of the stomach is a tissue membrane.  

Then we have connnective tissue membranes and epithelial membranes:

    Connective Tissue Membranes

The connective tissue membrane is composed only from connective tissues. These membranes encapsulate organs, examples arekidneys, and line our movable joints.

       Epithelial Membranes

An epithelial membrane will have epithelium attached to the layer that connects tissue, like the epidermis. Other epithelial membranes are the mucouses.

The two basic types of body membranes are connective tissue membranes and epithelial membranes. Connective tissue membranes encapsulate organs and line movable joints, with synovial membranes being a specific example. Epithelial membranes line passageways leading to the body's exterior, line closed internal cavities, and form the skin; they include mucous, serous, and cutaneous membranes.

Body membranes are thin layers or sheets of cells that cover and protect various parts of the body. There are two basic types of these membranes: connective tissue and epithelial membranes.

Connective tissue membranes include synovial membranes and are mostly found encapsulating organs, such as the kidneys, and lining our movable joints. A characteristic example of this type is the synovial membrane, which lines the cavity of freely movable joints (like the shoulder, elbow, and knee) and helps reduce friction during movement.

Epithelial Membranes include mucous, serous, and cutaneous membranes. Mucous membranes contain glands and line the passageways that lead to the exterior of the body. Serous membranes secrete a lubricating fluid and are found lining the cavities not open to the exterior, such as the thoracic and abdominal cavities, as well as enveloping internal organs within these cavities. Cutaneous tissue refers to skin – a protective barrier covering the body's external surface.

Answer:

The correct answer here is e) more than one apply here

Explanation:

Look cortisol is very essential for a persons health as this is the hormone ( which is produced in adrenal glands) which sees how the body is going to respond to the stress. This cortisol hormone helps in controlling the blood pressure, controlling sugar levels in our blood etc.

But if the levels of cortisol are increase then the CRH (Corticotropin releasing hormone) and ACTH(Adrenocorticotropic hormone) also increases which can lead to the corticotrop tumor.

With the increase in the cortisol levels , it will lead to the decrease in the inflammation and also our body won't react to the stress properly, our blood sugar levels and stress levels with blood pressure would increase which leads to bad effects on the heart.

So therefore we can say that the option e is correct.

Answer:

The blood pressure is the measure of the strength by which the blood pushes against the side of the blood vessels when it circulates inside the body.

Explanation:

When heart beats, the heart pumps the blood around the body to supply energy/oxygen to the various parts of the body where it is needed.

As the blood circulates, it pushes against sides of blood vessels. The strength of pushing of the blood is measured by blood pressure. Most of the pressure is due to the work done by the heart in pushing the blood.

It is measure by using sphygmomanometer. Two numbers are used to measure the blood pressure.

Systolic blood pressure is the first digit used for measuring blood pressure and it measures pressure in blood vessels when heart beats.

Disystolic blood pressure is the second digit used for measuring blood pressure and it measures the pressure of blood in the vessels when heart is resting between beats.

Answer:

Endochondral ossification can be defined as two essential processes by which the development of mammalian skeletal system takes place.

During this process the bone tissue of the body is created. Cartilage is present during the time of endochondral ossification.

There are five major steps involved in this process.

Final answer:

Endochondral ossification is the development of bone from hyaline cartilage, excluding the flat bones of the skull. It follows five steps, starting with mesenchymal cells differentiating into chondrocytes and culminating with the formation of secondary ossification centers, while maintaining cartilage at the growth plates and as articular cartilage.

Explanation:

Endochondral Ossification Steps

At the conclusion of endochondral ossification, cartilage remains solely in two key areas: the epiphyseal (growth) plates and as articular cartilage, which is essential for joint function.

Answer:

The answer is A: mean arterial pressure.

Explanation:

The difference between systolic blood pressure and diastolic blood pressure results in mean blood pressure. It is considered as the perfusion pressure of body tissues and organs. Its normal value must be between 60 or 80 mmHg to maintain a good perfusion. Below these values there is a risk that the tissues have ischemia.

Answer:

The test to determine the blood group is called ABO typing. A blood sample is mixed with the antibodies against blood type A and type B. Then, the sample is checked to see if the blood cells stick or not. If the blood cells remain together that means that the blood reacted with one of the antibodies.

Answer:

Its an abnormal rhythm of the heart at a rate greater than 100 beats per minute

Explanation:

Polymorphic ventricular tachycardia is a type of heart rate disorder where there is abnormal electrical activity causing the heart to beat faster while maintaining multiple patterns. It disrupts the heart's function, making it less effective at pumping blood. Treatment options include defibrillators, medication, and possibly surgery.

Polymorphic ventricular tachycardia is a form of ventricular tachycardia, a condition where the heart beats at a fast rate because of abnormal electrical activity. Such a state prevents the heart from effectively pumping blood which can lead to significant complications, up to and including brain death if left untreated. Ventricular tachycardia is regarded as a medical emergency, often addressed as "code blue" in a hospital setting.

In the case of polymorphic ventricular tachycardia, the electrical variations seen on an Electrocardiogram (ECG) have multiple different forms. That's why it is called "polymorphic". This condition can make the heart even more susceptible to disturbances and pump blood less efficiently.

Treatments vary, but the use of defibrillators, devices that apply an electrical charge to the heart to establish a normal rhythm, is common. This treatment effectively stops the heart so that it can reestablish a normal conduction cycle. Other potential treatments, depending on the cause, may include medications, implantable cardioverter defibrillators, ablation, or surgery.

Answer:

The correct answer is option D. all of the above.

Explanation:

The skeletal muscle is a type of striated muscle, that is controlled by the somatic nervous system. Tendons are the collagen fiber that binds these muscles to the bones.

Skeletal muscles are arranged in antagonistic pairs so if a muscle helps a joint to move so the other muscle can bring it to its original resting position. The point where muscle binds to an immovable bone called the origin of the muscle and the point where muscle attached to a movable bone its termed as insertion.

Thus, the correct answer is option D.

The function of the following tissues are as follows:

Stratified squamous keratinized epithelium: These tissues cover the surface of the body and present at hair and skin. These tissues are keratinized to protect the surface of body from abrasion.

Simple squamous epithelium:  This tissue contain the single layer of flat cells. These tissues are thin and has the ability to pass some selected molecules through the cells.

Hyaline cartilage: Hyaline cartilage contains large amount of collagen that provides support and flexibility to the tissues.

Bone: Bones are made up of calcified material, phosphates and various inorganic ions. Bones provide stiffness and supports the weight of muscles in our body.

Answer and explanation :

there are many problem due to lack of pneumotaxic and stetch receptor neurons on ventilation

DUE TO LACK OF PNEUMOTAXIC  CENTER :

DUE TO LACK OF STRETCH RECEPTOR :

Final answer:

The absence of pneumotaxic and stretch receptor neurons would disrupt the regulation of breathing rate and the ventilatory response to physical activity, affecting the body's ability to maintain homeostasis during rest and exercise.

Explanation:

The lack of pneumotaxic and stretch receptor neurons has a significant effect on ventilation. The pneumotaxic center, located in the pons, helps regulate the rate of breathing by inhibiting the activity of the neurons in the dorsal respiratory group. Stretch receptors in muscles, joints, and tendons, known as proprioceptors, provide a stimulus that can trigger the respiratory centers of the brain to adjust breathing during activities like exercise.

Without the pneumotaxic center, the body may lose the ability to properly regulate the rate of breathing, possibly leading to an erratic or inefficient breathing pattern. The absence of proprioceptive feedback from the stretch receptors could result in a diminished respiratory response to physical activity, thereby affecting the necessary increase in ventilation that generally corresponds with exercise. Overall, these deficiencies can impair the body's ability to maintain homeostasis during various states of physical activity and rest.

Answer:

Kupffer cells, also known as stellate macrophages due to their particular structure while viewed under a microscope, were first identified by scientist Karl Wilhelm von Kupffer, after whom the cells were named, in 1876.

These cells, whose origin is in the yolk sack during fetal development, later on move to the liver where they will stay and further differentiate into their mature versions.

These cells are part of the liver cells, and are found particularly on the walls of the sinusoids, where they perform their two most important tasks. First, these cells are part of the immune system, as they are essentially macrophages. However, their role is pretty unique, as they are responsible not just for phagocytosis of invading bacteria, and other pathogens, and initiating immune responses, but also, this cell plays a role in decomposing red blood cells who are dying, and taking up the hemoglobin from them to further break that into reusable globin, and the heme group, from which iron is further extracted to be re-used and also to create bilirrubin, a part of bile.

Finally, these cells have been found to be connected to hepatic cirrhosis, as in their process of detoxifying ethanol, they produce toxins that force the liver cells to produce collagen, and thus to become fibrous.

Answer:

The correct answer to the question: Which of the following instruments is often used to grasp the intestines, would be: C: Babcock clamps.

Explanation:

Surgery on the abdominal cavity, be it open, or through laparoscopy, is major, and requires specialized equipment, as destabilazation of the patient will be very fast, especially with the loss of temperature, and the possibility of coagulopathies. There are many types of equipment and tools that are required during a GI tract surgery, and most of them had to do with either the careful manipulation of the blood vessels around the abdominal cavity, or the intestines. In the case of the intestines, the instrument that must always be present are the Babcock clamps which are used to hold the intestinal tissue during surgery.

Final answer:

An increase in blood viscosity increases the thickness of blood, making it flow less easily through blood vessels, which in turn increases peripheral resistance. The correct answer to the statement is 'True.'

Explanation:

An increase in blood viscosity will indeed cause an increase in peripheral resistance. This is because viscosity refers to the thickness or stickiness of a fluid, and blood is no exception. When blood viscosity increases, it flows less easily through the blood vessels. Just like sipping a milkshake through a straw would require more effort compared to sipping water, more effort (or higher pressure) is needed to pump thicker blood through the circulatory system.

Think of the circulatory system as a series of pipes: if the 'fluid' inside the pipes becomes thicker, it's naturally going to flow with more difficulty. This difficulty is what's referred to as resistance. Increased viscosity thus increases resistance and decreases flow. Therefore, the correct answer to the given statement would be:

a. True

D) dense regular CT

Explanation:

There are four basic types of animal tissue:

Epithelial tissue, Muscle tissue, Nervous tissue and Connective tissue.

Connective tissues are found in between the other tissues in the body everywhere.The functions of connective tissues are:

1. Binding and support

2. Protection

3. Insulation

4. Transportation (for blood)

There are four main types of CT:

Connective Tissue Proper: 1. Loose connective (areolar, adipose, reticular) 2. Dense connective tissue (regular, irregular, elastic).

Bone Tissue: 1. Compact bone 2. Spongy bone.

Cartilage: 1. Hyaline cartilage 2. Elastic cartilage 3. Fibrocartilage.

Blood

Bone and cartilage are supportive and structural connective tissues which provide strength and structure to body. They also protect the soft tissues.

Hence, D) Dense regular CT is not a structural/supporting connective tissue.
