Q. No.The location of kidneys in humans can be best described as:
| 1. | between last thoracic and third lumbar vertebra close to dorsal inner wall of abdominal cavity |
| 2. | between last thoracic and third lumbar vertebra close to ventral inner wall of abdominal cavity |
| 3. | between 10th thoracic and third lumbar vertebra close to dorsal inner wall of abdominal cavity |
| 4. | between 10th thoracic and third lumbar vertebra close to ventral inner wall of abdominal cavity |
Extension of renal cortex between the medullary pyramids is called as:
| 1. Juxta-glomerular apparatus | 2. Macula densa |
| 3. Columns of Bertini | 4. Ducts of Bellini |
The branch of renal artery that directly supplies the glomerulus is the:
| 1. | efferent arteriole | 2. | interlobular artery |
| 3. | arcuate artery | 4. | afferent arteriole |
Malpighian body or the renal corpuscle is made up of:
1. Glomerular capillaries and PTCN
2. Bowman's capsule and renal tubules
3. Afferent and efferent arterioles
4. Glomerular capillaries and Bowman's capsule
The functional unit of the human kidney is the:
| 1. | glomerulus | 2. | Malpighian body |
| 3. | nephron | 4. | medullary pyramids |
A series of straight capillaries in the medulla that lie parallel to the loop of Henle are called:
| 1. | arcuate arteries | 2. | efferent arterioles |
| 3. | afferent arterioles | 4. | vasa recta |
In the male, urethra serves to:
1. transport urine from kidney to bladder
2. transport sperms to ejaculatory ducts
3. store urine and sperms
4. discharge semen and urine
Consider the two statements:
| I: | The process of filtration at Malpighian body is regarded as ultrafiltration. |
| II: | Blood is filtered so finely that all constituents of plasma pass into the lumen of Bowman’s capsule. |
| 1. | Both I and II are correct and II explains I |
| 2. | Both I and II are correct but II does not explain I |
| 3. | I is correct but II is incorrect |
| 4. | I is incorrect but II is correct |
