Which hormone promotes RBC production in the bone marrow?

Correct option is D

The correct answer is (d) Erythropoietin.
· Erythropoietin (EPO) is the hormone responsible for stimulating the production of red blood cells (RBCs) in the bone marrow.
· It is primarily produced by the kidneys in response to low oxygen levels in the blood.
· When the oxygen levels are low, the kidneys release erythropoietin, which then signals the bone marrow to increase RBC production. This process is crucial for maintaining adequate oxygen transport throughout the body.
· Erythropoietin plays an essential role in regulating RBC production and is used medically to treat anemia, particularly in patients with chronic kidney disease.
Additional Knowledge:
· Cholecystokinin: A hormone that stimulates the digestion of fats and proteins by promoting bile and enzyme release from the gallbladder and pancreas.
· Serotonin: A neurotransmitter that regulates mood, appetite, and sleep, not involved in RBC production.
· Somatostatin: A hormone that inhibits the release of several other hormones like growth hormone and insulin, not related to RBC production.
