Q. Which among the following does not occur in response to the release of angiotensin II?

NTA AbhyasNTA Abhyas 2020

Solution:

As the blood pressure decreases, Juxtaglomerular apparatus cells (JGA) releases Renin enzyme to activate Renin-Angiotensinogen-Aldosterone-System (RAAS).
Renin converts Angiotensinogen into the active form Angiotensin-I, which is further converted into Angitensin-II by the enzyme Angiotensin converting enzyme (ACE).
The angiotensin II hormone aids in the reabsorption of sodium in the Na-H exchange that takes place in the proximal convoluted tubule.
Angiotensin-II increases the synthesis of Aldosterone and its subsequent release. It also raises the blood pressure directly by the constriction of vessels (vasoconstriction) and thereby stimulates the sodium reabsorption by PCT.
