Which of the following causes an increase in sodium reabsorption in distal convoluted
tubule?
1. Increase in aldosterone levels
2. Increase in antidiuretic hormone levels
3. Decrease in aldosterone levels
4. Decrease in antidiuretic hormone levels
Which one of the following correctly explains the function of a specific part of a human
nephron?
1. Henle's loop - most reabsorption of the major substances from the glomerular filtrated
2. Distal convoluted tubule - reabsorption of ions into the surrounding blood capillaries
3. Afferent arteriole - carries the blood away from the glomerulus towards renal vein
4. Podocytes- create minute spaces (slit pores) for the filtration of blood into the
Bowman's capsule
Which one of the following statements is correct with respect to kidney function
regulation?
1. Exposure to cold temperatures stimulates ADH release
2. An increase in glomerular blood flow stimulates the formation of angiotensin II
3. During summer when the body loses a lot of water by evaporation, the release of ADH is
suppressed
4. When someone drinks a lot of water ADH release is suppressed
Which one of the following statements in regard to excretion by the human kidneys is correct?
1. | Descending limb of loop of Henle is impermeable to water |
2. | Distal convoluted tubule is incapable of reabsorbing HCO3 |
3. | Nearly 99 per cent of the glomerular filtrate is reabsorbed by the renal tubules |
4. | Ascending limb of loop of Henle is impermeable to electrolytes |
The principal nitrogenous excretory compound in humans is synthesised.
1. in kidneys but eliminated mostly through liver
2. in kidneys as well as eliminated by kidneys
3. in liver and also eliminated by the same through bile
4. in the liver, but eliminated mostly through kidneys
Which one of the following is correct regarding the excretion?
1. Large amount of water from renal filtrate is reabsorbed in DCT and a less amount is reabsorbed by PCT.
2. The descending limb of loop of Henle is almost impermeable to salts.
3. Malpighian corpuscle is found in medulla region of kidney
4. The colour of urine is pale yellow and is slightly alkaline in nature.
Which of the following process of urine formation takes place all along the renal tubule and collecting duct?
1. Ultrafiltration and tubular reabsorption
2. Ultrafiltration and tubular secretion
3. Tubular reabsorption and secretion
4. Anti-current mechanism and reabsorption
Which of the following does not favor the formation of large quantities of dilute urine?
1. Alcohol
2. Caffeine
3. Renin
4. Atrial-natriuretic factor
The part of nephron involved in active reabsorption of sodium is
1. distal convoluted tubule
2. proximal convoluted tubule
3. Bowman's capsule
4. descending limb of Henle's loop
Which of the following statements is correct?
1. The ascending limb of loop of Henle is impermeable to water
2. The descending limb of loop of Henle is impermeable to water
3. The ascending limb of loop of Henle is permeable to water
4. The descending limb of loop of Henle is permeable to electrolytes
