Options
- AReabsorption of Na + and water from renal tubules due to aldosterone
- BAtrial natriuretic factor causes vasoconstriction
- CDecrease in secretion of renin by JG cells
- DMore water reabsorption due to undersecretion of ADH
Correct answer
A. Reabsorption of Na + and water from renal tubules due to aldosterone
Step-by-step solution
The JGA secretes an enzyme rennin in response to a variety of stimuli such as the decreased flow of fluid and NaCl to macula densa, decreased stretch of JG cells, and increased frequency of nerve impulses in the renal sympathetic nerves. The rennin, after being released into the blood acts on a plasma protein called angiotensinogen secreted by the liver and converting enzyme converts it into angiotensin-II. This is an active hormone having the following functions. a. It is a vasoconstrictor, that constricts the eff
