1. Ascending limb of loop of Henle
2. Descending limb of loop of Henle
3. Distal convoluted tubule
4. Collecting duct
Match the items given in Column I with those Column II and select the correct option given below:
| Column I | Column II | ||
| (Function) | (Part of the Excretory system) | ||
| (a) | Ultrafiltration | (i) | Henle's loop |
| (b) | Concentration of urine | (ii) | Ureter |
| (c) | Transport of urine | (iii) | Urinary bladder |
| (d) | Storage of urine | (iv) | Malpighian corpuscle |
| (v) | Proximal convoluted tubule | ||
| Options: | (a) | (b) | (c) | (d) |
| 1. | (iv) | (v) | (ii) | (iii) |
| 2. | (iv) | (i) | (ii) | (iii) |
| 3. | (v) | (iv) | (i) | (ii) |
| 4. | (v) | (iv) | (i) | (iii) |
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 amount of urine produced is generally increased when there is:
1. increased ADH secretion
2. increased atrial natriuretic hormone secretion
3. increased aldosterone secretion
4. sympathetic stimulation of the renal arteries
Which statement does not correctly describe the path of urine flow?
1. ducts in each renal papilla drain into a minor calyx
2. the minor calyces merge to form a major calyx
3. the major calyces combine to form the renal pelvis
4. the renal pelvis conveys urine directly to the urethra
The concentrations of which plasma electrolyte is not regulated mainly by the kidneys?
1. hydrogen
2. potassium
3. iron
4. Bicarbonate
Which section of the nephron follows the ascending limb of the loop of Henle?
1. descending limb of the loop
2. proximal convoluted tubule
3. distal convoluted tubule
4. collecting duct
Within the renal tubule, two hormones play a role in determining the final volume and sodium concentration of the urine. The hormone ____ regulates sodium reabsorption, while ______ regulates water reabsorption.
1. aldosterone; antidiuretic hormone (ADH)
2. cortisol; atrial natriuretic peptide
3. renin; angiotensin II
4. antidiuretic hormone (ADH); epinephrine
