Q. No.The Bowman's capsule and glomerulus constitute the:
1. Malpighian tubule
2. Renal corpuscle
3. Nephron
4. Collecting system
The proximal convoluted tubule of the nephron is lined by:
1. simple ciliated cuboidal epithelium
2. simple ciliated columnar epithelium
3. compound cuboidal brush bordered epithelium
4. simple cuboidal brush bordered epithelium
A capillary network around the renal tubule is formed by:
| 1. | Afferent arteriole | 2. | Efferent arteriole |
| 3. | Vasa recta | 4. | Arcuate artery |
The average weight of the human kidney varies between:
| 1. | 80 – 120 gm | 2. | 120 – 170 gm |
| 3. | 180 – 200 gm | 4. | 225 – 245 gm |
The main physiological stimulus for vasopressin release is
| 1. | Blood volume | 2. | Plasma osmolality |
| 3. | Blood pressure | 4. | Stroke volume |
All the following are the physiological effects of angiotensin II except:
1. Vasoconstriction in renal artery and afferent arteriole
2. Vasodilation in efferent arteriole
3. Increased sodium absorption in PCT
4. Stimulation of adrenal cortex to release aldosterone
1. Juxta-glomerular apparatus
2. Macula densa
3. Columns of Bertini
4. Ducts of Bellini
What is the number of times that the human kidneys can maximally concentrate the initial filtrate?
| 1. | 2 | 2. | 4 |
| 3. | 6 | 4. | 8 |
Aldosterone can be secreted by adrenal cortex when it is stimulated most directly by:
| 1. | ADH | 2. | Renin |
| 3. | Angiotensin | 4. | ANF |
As the filtrate passes upward in the ascending limb of loop of Henle:
| 1. | it gets diluted due to the reabsorption of water from medullary interstitium |
| 2. | it gets diluted due to the passage of electrolytes to medullary interstitium |
| 3. | it gets concentrated due to the reabsorption of electrolytes from medullary interstitium |
| 4. | it gets concentrated due to the passage of water to medullary interstitium |
