Which of the following statements is correct?
| 1. | The descending limb of loop of Henle is impermeable to water. |
| 2. | The ascending limb of loop of Henle is permeable to water. |
| 3. | The descending limb of loop of Henle is permeable to electrolytes. |
| 4. | The ascending limb of loop of Henle is impermeable to water. |
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
2. Hepatic Vein
3. Hepatic Portal Vein
4. Renal Vein
Which of the following does not favour the formation of large quantities of dilute urine?
2. Caffeine
3. Renin
4. Atrial-natriuretic factor
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
Figure shows a human urinary system with structures labelled A to D. Select option which correctly identifies them and gives their characteristics and/or functions.
| 1. | B-pelvis - broad funnel-shaped space inner to the hilum, directly connected to loops of Henle. |
| 2. | C- Medulla- inner zone of kidney and contains complex nephrons. |
| 3. | D- Cortex- outer part of the kidney and does not contain any part of nephrons. |
| 4. | A- Adrenal gland- located at the anterior part of the kidney; secretes catecholamines which stimulate glycogen breakdown. |
The maximum amount of electrolytes and water (70-80%) from the glomerular filtrate is reabsorbed in which part of the nephron?
1. Ascending limb of the loop of Henle
2. Distal convoluted tubule
3. Proximal convoluted tubule
4. Descending limb of the loop of Henle
| 1. | Henle’s loop – most reabsorption of the major substances from the glomerular filtrate |
| 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 |
1. birds and annelids
2. amphibians and reptiles
3. insects and amphibians
4. reptiles and birds
