Question

Hormone that does not cause vasoconstriction?

Answer 1

Answer:

The correct answer is option C-ANP (Atrial natriuretic peptide).

Explanation:

Vasoconstriction is the narrowing of the blood vessels which can stop or block the blood flow.

Vasoconstriction reduces the urine formation during stress conditions through the action of hormones like ADH (anti-diuretic hormone), norepinephrine, epinephrine and angiotensin II produced via the sympathetic nervous system.

The atrial natriuretic hormone (ANP) is a cardiac hormone produced to lower the blood pressure or reduce blood plasma through vasodilation, increased vascular permeability and increase renal excretion.  

Thus, option C is the correct answer.
