- A.
Secretion of bile
- B.
Storage of glycogen
- C.
Storage of bile
- D.
Detoxification of xenobiotics
- E.
Synthesis of clotting factors
Correct Answer
C. Storage of bileExplanation
The liver performs various functions, including the secretion of bile, storage of glycogen, detoxification of xenobiotics, and synthesis of clotting factors. However, the storage of bile is not a function of the liver. Bile is produced by the liver and stored in the gallbladder until it is needed for digestion.Rate this question:

________ hormone is released in response to hypoxia in renal circulation,
- A.
Calcitriol
- B.
Renin
- C.
Aldosterone
- D.
Vasopressin
- E.
Erythropoitin
Correct Answer
E. ErythropoitinExplanation
Erythropoietin is released in response to hypoxia in renal circulation. Hypoxia refers to a deficiency of oxygen in the tissues, and the kidneys play a crucial role in regulating oxygen levels in the body. Erythropoietin is a hormone produced by the kidneys that stimulates the production of red blood cells in the bone marrow. When the kidneys detect low oxygen levels, they release erythropoietin, which then stimulates the bone marrow to produce more red blood cells. This helps increase the oxygen-carrying capacity of the blood and restore normal oxygen levels in the body.Rate this question:

- A.
Removal of waste from the body
- B.
Maintenance of acidbase balance
- C.
Production of hormones
- D.
Regulation of blood pressure
- E.
Storage of glycogen
Correct Answer
E. Storage of glycogenExplanation
The kidney is not responsible for the storage of glycogen. Glycogen is a form of glucose storage in the liver and muscles, not in the kidneys. The kidneys primarily function to remove waste from the body, maintain acid-base balance, produce hormones, and regulate blood pressure.Rate this question:

The following statements about liver failure are correct except
- A.
Plasma level of ammonia will rise
- B.
Severe hyperglycaemia develops
- C.
The digestion and absorption of fats is impaired
- D.
Prolonged clotting time of bleeding wound occurs
- E.
Acid base homeostasis is destabilized
Correct Answer
E. Acid base homeostasis is destabilizedExplanation
The correct answer is "Acid base homeostasis is destabilized". In liver failure, the plasma level of ammonia will rise due to impaired detoxification by the liver. Severe hyperglycemia develops because the liver is unable to store and release glucose properly. The digestion and absorption of fats is impaired because the liver produces bile, which is necessary for fat digestion. Prolonged clotting time of bleeding wounds occurs because the liver produces clotting factors. However, acid base homeostasis is not directly affected by liver failure.Rate this question:

______ is the function of an antidiuretic
- A.
Reduces volume of urine
- B.
Increase volume of urine
- C.
Causes the Kidney to excrete more watet
- D.
Causes the bladder to retain less water
- E.
All of the above
Correct Answer
A. Reduces volume of urineExplanation
The function of an antidiuretic is to reduce the volume of urine. Antidiuretics act on the kidneys to decrease the amount of water excreted in urine, leading to a reduction in urine volume. This helps in conserving water in the body and preventing excessive loss of fluids.Rate this question:
-

_______ is an abnormal constituent of urine
- A.
Urea
- B.
Creatinine
- C.
Ammonia
- D.
Protein
- E.
Uric acid
Correct Answer
D. ProteinExplanation
Protein is an abnormal constituent of urine because under normal circumstances, the kidneys filter out waste products from the blood, including protein. However, when there is damage or dysfunction in the kidneys, protein may leak into the urine, which is known as proteinuria. This can be a sign of kidney disease or other underlying health conditions. Therefore, the presence of protein in urine is considered abnormal.Rate this question:

A condition in which the liver becomes infused with fibrous tissues and unable to repair itself is known as
- A.
Hepatitis
- B.
Cirrhosis
- C.
Jaundice
- D.
Hepatoma
- E.
None of the above
Correct Answer
B. CirrhosisExplanation
Cirrhosis is a condition where the liver becomes filled with fibrous tissues and is unable to regenerate or repair itself. This can occur due to chronic liver diseases such as hepatitis or alcoholism. As a result, the liver's normal structure is disrupted, leading to impaired liver function. Symptoms of cirrhosis can include fatigue, jaundice, fluid retention, and confusion. If left untreated, cirrhosis can progress to liver failure. Therefore, cirrhosis is the correct answer in this case.Rate this question:

The kidney secretes ________ for the purpose of stimulating bone marrow activity
- A.
Renin
- B.
Aldosterone
- C.
Erythropoitin
- D.
Somatomedin
- E.
Angiotensinogen
Correct Answer
C. ErythropoitinExplanation
The kidney secretes erythropoietin for the purpose of stimulating bone marrow activity. Erythropoietin is a hormone that regulates the production of red blood cells in the bone marrow. When the kidney senses low oxygen levels in the blood, it releases erythropoietin, which then stimulates the bone marrow to produce more red blood cells. This helps to increase the oxygen-carrying capacity of the blood and maintain normal oxygen levels in the body.Rate this question:
-
- 13.
Which process is most affected by blood pressure
- A.
Tubular secretion
- B.
Tubular reabsorption
- C.
Glomerular filtration
- D.
Tubular excretion
- E.
Loop of Henle diffusion
Correct Answer
C. Glomerular filtrationExplanation
Blood pressure is most affected by glomerular filtration. Glomerular filtration is the process by which fluid and solutes are filtered from the blood in the glomerulus of the kidney into the renal tubules. Blood pressure plays a crucial role in this process as it determines the force at which the blood is pushed through the glomerulus. Higher blood pressure will result in increased filtration, while lower blood pressure will decrease filtration. Therefore, blood pressure has a significant impact on the rate of glomerular filtration.Rate this question:

Eating large amount of meat will increase the level of ________ in the blood
- A.
Protein
- B.
Creatinine
- C.
Uric acid
- D.
Urea
- E.
Water
Correct Answer
D. UreaExplanation
When we consume large amounts of meat, our body breaks down the protein in the meat into amino acids. These amino acids are then converted into ammonia, which is toxic to the body. To eliminate this ammonia, our liver converts it into urea, which is a waste product that is excreted through urine. Therefore, eating large amounts of meat will increase the level of urea in the blood.Rate this question:

______ is the functional filtration unit in the kidney
- A.
Renal tubule
- B.
Renal corpuscle
- C.
Nephron
- D.
Glomerulus
- E.
Proximal and distal convoluted tubule
Correct Answer
D. GlomerulusExplanation
The glomerulus is the functional filtration unit in the kidney. It is a network of tiny blood vessels called capillaries that filter waste products, excess water, and other substances from the blood. The glomerulus is located in the renal corpuscle, which is part of the nephron. The nephron is the basic structural and functional unit of the kidney, responsible for filtering and processing blood to produce urine. The proximal and distal convoluted tubules are also part of the nephron, but they are not the primary filtration unit.Rate this question:

- C.
Is secreted in response to increased blood volume
- D.
Stimulates Sodium and potassium retention
- E.
None of the above
Correct Answer
C. Is secreted in response to increased blood volumeExplanation
Aldosterone is a hormone that is secreted in response to increased blood volume. When blood volume increases, the body needs to regulate the balance of sodium and potassium ions. Aldosterone stimulates the retention of sodium and the excretion of potassium, helping to maintain the balance and regulate blood pressure. Therefore, the correct answer is "Is secreted in response to increased blood volume."Rate this question:

Correct Answer
N/A - 19.
The three interrelated processes of urine formation are
- A.
Filtration, secretion and excretion
- B.
Secretion, reabsorption and micturition
- C.
Filtration, storage and excretion
- D.
Excretion, storage and micturition
- E.
Fitration, reabsorption and secretion
Correct Answer
E. Fitration, reabsorption and secretionExplanation
The correct answer is "Filtration, reabsorption, and secretion." This is because urine formation involves the filtration of blood in the kidneys, where waste products and excess substances are removed from the blood and filtered into the renal tubules. Reabsorption then occurs, where useful substances such as water, glucose, and ions are reabsorbed back into the bloodstream. Finally, secretion takes place, where additional waste products and substances that were not filtered initially are added to the filtrate in the renal tubules.Rate this question:

Arrange the following to trace the path of filtrate through a renal tubule: 1) proximal convoluted tubule 2) distal convoluted tubule 3) ascending limb of nephron loop 4) descending limb of nephron loop
- A.
1,2,3,4
- B.
2,3,4,1
- C.
1,4,3,2
- D.
3,2,1,4
- E.
4,3,1,2
Correct Answer
C. 1,4,3,2Explanation
The correct order to trace the path of filtrate through a renal tubule is as follows: 1) proximal convoluted tubule, 2) descending limb of nephron loop, 3) ascending limb of nephron loop, and 4) distal convoluted tubule. The proximal convoluted tubule is the first part of the renal tubule where reabsorption of water, ions, and nutrients occurs. The filtrate then enters the descending limb of the nephron loop, where water is reabsorbed. Next, the filtrate moves through the ascending limb of the nephron loop, where ions are reabsorbed. Finally, the filtrate reaches the distal convoluted tubule, where further reabsorption and secretion take place.Rate this question:
