When oxygen levels are low the kidneys secrete?

When kidneys don’t have enough oxygen, they produce a protein called erythropoietin (EPO), which stimulates red blood cell production. “Athletes know that the best way to increase your red blood cell count is by either injecting EPO – doping – or going to high altitudes,” Chandel explained.

What triggers the release of erythropoietin?

These cells release erythropoietin when the oxygen level is low in the kidney. Erythropoietin stimulates the bone marrow to produce more red blood cells which in turn increases the oxygen-carrying capacity of the blood. EPO is the prime regulator of red cell production.
