Question

23 multiple choice 2 points a drop in blood pressure will signal the cascade of enzymes and hormones to return homeostasis. the first enzyme released into aldosterone. vasopressin. atrial natriuretic peptide. renin.

Explanation:

When blood pressure drops, the kidneys release renin first. Renin initiates the renin - angiotensin - aldosterone system (RAAS). Aldosterone is released later in the cascade. Vasopressin is also involved in blood pressure regulation but not the first - released enzyme. Atrial natriuretic peptide acts to lower blood pressure and is not the initial response to a drop in blood pressure.

Answer:

D. renin
