What is the substance that stimulates the production of red blood cells? Which is the organ that secretes it? Under what conditions does this secretion increase?
by

1 Answer

Answer :

The substance that stimulates the production of red blood cells by the bone marrow is erythropoietin. Erythropoietin is a hormone secreted by the kidneys. Its secretion is increased when there is deficient tissue oxygenation (tissue hypoxia) caused either by reduced oxygen availability (as it occurs in high altitudes) or by internal diseases, as in pulmonary diseases.
