What is the function of Angiotensin $II$?
✓
Answer
Functions of Angiotensin $II:$
$1.$ It constricts arterioles in kidney thereby reducing blood flow and increasing blood pressure.
$2.$ It stimulates $\text{PCT}$ cells to enhance reabsorption of $Na^+, Cl^–$ and water.
$3.$ It stimulates adrenal cortex to release another hormone called aldosterone that stimulates $\text{DCT}$ and collecting ducts to reabsorb more Na and water, thereby increasing blood volume and pressure.
