Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The kidneys help control the rate of red blood cell formation by secreting
A
aldosterone
B
erythropoietin
C
renin
D
antidiuretic hormone
Explanation: 

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. PO2 directly regulates EPO production. The lower the pO2, the greater the production of EPO.

Detailed explanation-2: -Erythropoietin, which is produced by peritubular capillary lining cells of the kidney, is critical to the production of red blood cells. Endogenously produced erythropoietin circulates in the plasma to act on specific target cells in the marrow through cell surface receptors.

Detailed explanation-3: -Healthy kidneys produce a hormone called erythropoietin or EPO, which stimulates the bone marrow to make red blood cells needed to carry oxygen (O2) throughout the body.

Detailed explanation-4: -The hormone erythropoietin (Epo) maintains red blood cell mass by promoting the survival, proliferation and differentiation of erythrocytic progenitors. Circulating Epo originates mainly from fibroblasts in the renal cortex. Epo production is controlled at the transcriptional level.
