Answer:
The correct answer will be- ADH alters the reabsorption of water and RAAS leads to the reabsorption of sodium ions.
Explanation:
To maintain the osmolarity of the blood in the human body, the body activates the RAAS pathway and the production of ADH.
RAAS pathway gets activated when the receptors sense low blood pressure in the body. This activates the production of renin from the juxtaglomerular cells of the body which converts the angiotensin to angiotensin I and later angiotensin II.
This allows the reabsorption of sodium ions in the blood through proximal and distal tubules in the nephron. This activates the synthesis of aldosterone which increase the permeability to sodium ions.
The Antidiuretic hormone helps regulate the low blood pressure by adding aquaporins to the distal tubule membrane which help absorb the water.
Thus, ADH alters the reabsorption of water and RAAS leads to the reabsorption of sodium ions is the correct
