Question

What are the Rates of red blood cell production in the bone marrow of different bones at different ages?

Answer 1

 The formation of a red blood cell from hemocytoblast takes about 2 days. The body makes about two million red blood cells every second.

Answer 2

• Erythropoietin is a hormone that stimulates the bone marrow to produce more red blood cells. The bone marrow also produces and releases more whiteblood cells in response to infections, and more platelets in response to bleeding.
