Select the correct statement.

Moderate

A

Renin converts angiotensinogen to angiotensin I in response to increased blood pressure.
B

Aldosterone causes reabsorption of ${Na}^{+}$ from DCT and decreases the blood pressure.
C

ADH can increase blood pressure by constricting blood vessels.
D

Angiotensin II decreases blood pressure by constricting the blood vessels.

Solution

ADH causes increase in blood pressure by constricting blood vessels.
The JGA plays a complex regulatory role. A fall in glomerular blood flow/glomerular blood pressure/GFR can activate the JG cells to release renin which converts angiotensinogen in blood to angiotensin I and further to angiotensin II. Angiotensin II, being a powerful vasoconstrictor, increases the glomerular blood pressure and thereby GFR.
Aldosterone causes reabsorption of ${Na}^{+}$ and water from the distal parts of the tubule. This also leads to an increase in blood pressure and GFR.
