Angiotensin II increases the secretion of ____, which stimulates reabsorption of sodium
|
|
aldosterone
|
|
|
erythropoietin
|
|
|
renin
|
|
|
antidiuretic hormone

Explanation:
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 stimulates the secretion of aldosterone is produced by the zona glomerulosa of the adrenal cortex (adrenal gland) and is involved in the retention of sodium in the kidney and other glands. The retention of water and sodium leads to increased blood volume, and thus blood pressure.
Detailed explanation-3: -Angiotensin II promotes expansion of the plasma volume by promoting renal sodium and water reabsorption.
