Question

How does aldosterone modify the chemical composition of urine

Answer 1

Answer: It modify the chemical composition of urine by increasing the taken in of Sodium ion and the ejection of potassium ion in the Kidney.

Explanation:

Aldosterone is an hormone secreted by the adrenal glands. It is the main regulator of salt and water balance in our body. It action has little metabolic reaction on fats, protein and carbohydrates.

In order to respond to the levels of sodium and potassium ions ,kidney releases Renin. The Renin with then act on ANGIOTESIONOGEN(a protein present in the plasma).

Renin changes ANGIOTENSINOGEN into ANGIOTENSIN 1 . Conversely, it is then converted into ANGIOTENSIN 2. ANGIOTENSIN 2 stimulates ALDOSTERONE from the Adrenal glands to increase the absorption of potassium and sodium ion in the collecting ducts.

URINE WILL HAVE FEWER SODIUM AND HIGHER POTASSIUM
