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.

b. Knee
c. Ankle
Answer:
a. hip
Explanation:
hope this help you above....
Final answer:
The coxal joint is the hip joint, a multiaxial ball-and-socket joint connecting the head of the femur to the acetabulum of the hip bone.
Explanation:
The coxal joint, commonly referred to as the hip joint, is a multiaxial ball-and-socket joint. This type of joint is classified by the connection between the head of the femur (thighbone) and the acetabulum of the hip bone. Such joints support a wide range of movement, including rotational movements, and are integral in bearing the body's weight and providing stability during activities like standing and walking. The hip joint's structure is designed to endure the substantial stress imposed on it, which is why it has a more limited range of motion compared to other multiaxial joints, such as the shoulder joint.

Which organ is both an endocrine and exocrine gland?
a. pancreas
b. pituitary
c. thyroid
d. pineal
Answer:
a. pancreas
Explanation:
As for exocrine organs, they release secretions. Since the pancreas is an exocrine gland its nervous or hormonal stimulation causes pancreatic secretions to be released into the duodenum through a duct. Together the secretions of alkaline and contain enzymes like lipase, amylase,etc . They are present in digestion. However the pancreas has two main functions, exocrine function and endocrine function. While exocrine cells of the pancreas produce enzymes that help digestion. An as endocrine , the islet cells of Langerhans inside the pancreas produce and secrete insulin and glucagon into the bloodstream.
The principle effect of ADH is to:
a. increase blood pressure in the glomerulus.
b. cause the release of renin.
c. inhibit aldosterone release.
d. increase the permeability of the distal convoluted tubule and collecting duct.
Answer:
The correct answer is option D.
Explanation:
Antidiuretic hormone or ADH is a hormone which helps the body to maintain the amount of water by reducing the loss of water through urine. This hormone is secreted by the hypothalamus which is stored in the pituitary gland.
The hormone acts by binding to the receptor which stimulates the insertion of "water channels" in the tubule membranes of kidney especially in Distal convoluted tubule and collecting duct. These kidney aquaporins help the absorption of water from the urine reducing the loss of water.
Thus, option D is the correct answer.
Answer: D) increase the permeability of the distal convoluted tubule and collecting duct.
Explanation:
The principle of ADH is to increased in the permeability of the distal convoluted tubule and collected duct as, the action of ADH on receptors enhances the water permeability the and insertion of aquaporin AQP-2 channel in the cell membrane. The main function of the ADH is to conserved water through kidney and get released in posterior pituitary gland.

A condition known as Pulmonary Hypertension is characterized by high blood pressure in the pulmonary circuit. Which chamber of the heart would this condition most directly affect, and why?
Pulmonary Hypertension directly affects the right ventricle of the heart due to the increased effort required to pump blood through the high-resistance pulmonary arteries, leading to potential hypertrophy and heart failure.
Explanation:The condition known as Pulmonary Hypertension is characterized by high blood pressure in the pulmonary circuit, specifically affecting the arteries that supply blood to the lungs. This condition most directly affects the right ventricle of the heart. In pulmonary hypertension, because the blood pressure in the lungs' arteries is elevated, the right ventricle must work harder to pump blood through these vessels. Over time, this increased workload can lead to the thickening of the right ventricle's muscular walls (hypertrophy), and potentially, the failure of the right ventricle.
Why the Right Ventricle is Affected
The right ventricle is responsible for pumping deoxygenated blood to the lungs for oxygenation.
Increased resistance in the pulmonary arteries forces the right ventricle to exert more effort in pumping blood.
This can lead to right ventricular hypertrophy and ultimately, right heart failure if untreated.
What are cell membranes composed of?
Answer:
Proteins, phospholipids and cholestorol
Explanation:

Increased temperature results in decreased O2 unloading from hemoglobin.
a. True
b. False
Answer: False.
Explanation:
The main function of hemoglobin is to transport oxygen to the various cells of the body. For this process to occur the oxygen from the lungs gets attached to the hemoglobin and travels throughout the body to reach at every possible place.
This hemoglobin also gets attached to the carbon dioxide from various cells of the body to lungs for gaseous exchange.
There are many factors that affect the loading and unloading of oxygen from hemoglobin. The increased temperature increases the rate of unloading of oxygen from hemoglobin and increased temperature does not favors loading of oxygen to hemoglobin.
Hence, the given statement is False.
Increased temperature actually increases the unloading of O2 from hemoglobin, not decreases. The temperature increase alters the hemoglobin protein shape to release oxygen more easily
Explanation:The statement is False. Increased temperature typically causes a greater unloading of O2 from hemoglobin. This happens because when the temperature increases, it alters the shape of the hemoglobin protein in a way that makes it release oxygen more easily.
This concept is known as the Bohr Effect, where high temperatures and an increase in the concentration of CO2 result in hemoglobin releasing more oxygen.
You could think of it as a mechanism that helps deliver more oxygen to vigorously working muscles that are producing more heat and CO2.

In the body, the steps of gas exchange,or respiration include:
a. pulmonary ventilation
b. external respiration
c. internal respiration
d. A and B are correct
e. A, B and C are correct
Answer:
The answer is E: A, B And C are correct.
Explanation:
The external respiration is that which occurs at the level of the pulmonary alveoli with the capillaries of the pulmonary vessels, producing an exchange of gases, releasing carbon dioxide from the blood to the alveolus, and in turn, this delivers oxygen.
The internal respiration is the one between the tissue capillaries and the cells where the blood releases the oxygen and receives the CO2, turning the oxygenated blood into deoxygenated.
The pulmonary ventilation on the other hand takes oxygen from the air we breathe and takes it to the lungs.
Respiration includes pulmonary ventilation, external respiration, and internal respiration. Pulmonary ventilation involves the movement of air in and out of the lungs. External respiration is the gas exchange between air and blood, while internal respiration is the gas exchange between blood and body tissues.
Explanation:The steps of gas exchange, also known as respiration, in the body indeed include pulmonary ventilation, external respiration, and internal respiration. Pulmonary ventilation is the process of moving air in and out of the lungs. External respiration is the gas exchange between the air in the lungs and the blood, while internal respiration refers to the gas exchange between the blood and body tissues.
