MICROANATOMY

Detailed explanation-1: -Erythropoietin (EPO) is a glycoprotein hormone, naturally produced by the peritubular cells of the kidney, that stimulates red blood cell production. Renal cortex peritubular cells produce most EPO in the human body.

Detailed explanation-2: -One such hormone is renin, which keeps blood pressure normal. If blood pressure falls, renin is secreted by the kidneys to constrict the small blood vessels, thereby increasing blood pressure.

Detailed explanation-3: -What hormones do the kidneys produce? The kidneys make two main hormones, vitamin D and erythropoietin. Vitamin D is essential for a number of different functions in the body. Most of the vitamin D that is in the blood is inactive and it is modified by the kidney and other tissues to activate it.

Detailed explanation-4: -Abstract. The kidney plays a pivotal role in the regulation of blood volume by controlling the plasma volume and red blood cell (RBC) mass.

Detailed explanation-5: -They are erythropoietin, renin, and calcitriol. Erythropoietin and renin are secreted by the juxtaglomerular cells of the kidney which are peptide hormones.
