THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Angiotensin II stimulates the synthesis and release of aldosterone from the zona glomerulosa (renin-angiotensin system). High levels of serum potassium directly stimulate aldosterone secretion from the zona glomerulosa.

Detailed explanation-2: -Angiotensin II Increase sodium reabsorption through increased activity of the Na-H antiporter in the proximal convoluted tubule (PCT)[21] Increasing sympathetic outflow from the central nervous system[22] Release of vasopressin from the hypothalamus[23]

Detailed explanation-3: -Angiotensin II causes the muscular walls of small arteries (arterioles) to constrict (narrow), which increases blood pressure. Angiotensin II also triggers your adrenal glands to release aldosterone and your pituitary gland to release antidiuretic hormone (ADH, or vasopressin).

Detailed explanation-4: -Angiotensin II promotes expansion of the plasma volume by promoting renal sodium and water reabsorption.
