Question

Explain the role of kidney in hormone secretion.

Answer 1

1. Renin, erythropoietin, and calcitriol are all produced by the kidney (calcitriol is the active form of vitamin D3).
2. Renin, in conjunction with angiotensin, helps to maintain blood pressure in the renal arteries through vasoconstriction.
3. Erythropoiesis is stimulated by erythropoietin.
4. Calcitrol aids in the absorption of calcium from the stomach.
