Which hormone control activity of zona glomerulosa of adrenal gland?

Solution
The correct option is C Renin
When the renal blood flow is reduced, juxtaglomerular cells in the kidneys convert the prorenin in the blood into renin and secrete into circulation. Plasma renin performs the conversion of angiotensinogen to angiotensin I. Angiotensin I is converted to angiotensin II by the enzyme angiotensin-converting enzyme. Angiotensin II causes blood vessels to constrict, resulting in increased blood pressure. Angiotensin II also stimulates the secretion of the hormone aldosterone from the zona glomerulosa of adrenal cortex. Aldosterone causes the tubules of the kidneys to increase the reabsorption of sodium and water into the blood. This increases the volume of fluid in the body, which also increases blood pressure.Thus, the correct answer is option A.
