a. Angiotensin

b. ADH

c. Aldosterone,

d. ANP

Answer 1

Ans:-

All of the given options are correct.

Angiotensin, ADH, Aldosterone and ANP all chemicals are involve or target the kidneys.

Explanation:-

- Angiotensin:- It stimulates the production of Aldosterone. Aldosterone causes sodium retention in the body. And in kidneys the Sodium retention triggered by the angiotensin changes the way the blood is filtered, that causes water re absorption in increase the blood volume.

- ADH:- It binds to the receptors on cells in the collecting ducts of the kidney and promotes water reabsorption back into the circulation.

- Aldosterone:- In kidneys, it increases Na+ reabsorption and K+ secretion in cells in the cortical collecting duct.

- ANP:- In kidneys it stimulates vasodialtion of the afferent arteriole of glomerulus ; this results in increased renal flow and an increase in glomerular filtration rate.
