Question

Select the CORRECT statement.

विकल्प

• Angiotensin II is a powerful vasodilator.

• Counter current pattern takes place in the PCT.

• Reduction in Glomerular Filtration Rate activates JG cells to release renin.

• ADH increases the osmolarity of blood.

Answer 1

Reduction in Glomerular Filtration Rate activates JG cells to release renin.

Explanation:

Vasodilation and blood pressure reduction are caused by atrial natriuretic factor (ANF). Blood flows in a counter current pattern through two limbs of the vasa recta. The osmolarity of blood is reduced by ADH.
