Question:
Which one of the following is NOT a function of Angiotensin II?
Which one of the following is NOT a function of Angiotensin II?
Show Hint
Angiotensin II raises blood pressure. Find the option that says the opposite.
Updated On: Nov 12, 2026
- It constricts arterioles in the kidney.
- It stimulates cells of PCT to enhance reabsorption.
- It stimulates the adrenal cortex to release aldosterone.
- It lowers blood pressure.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Renin from the JGA converts angiotensinogen into angiotensin I, which ACE changes into angiotensin II.
Step 2: Actions of angiotensin II
It is a strong vasoconstrictor and narrows arterioles, including those of the kidney. It increases sodium and water reabsorption from the PCT. It also stimulates the adrenal cortex to release aldosterone.
Step 3: Effect on pressure
All these actions raise blood pressure. So lowering blood pressure is not a function of angiotensin II.
Final Answer:
Lowering of blood pressure is not a function of angiotensin II. \[ \boxed{\text{(D) }\text{It lowers blood pressure.}} \]
