Question #ac074

Answer 1

No

Explanation:

Red blood cells(RBC's) are produced in the bone marrow. A Hematopoietic stem cell is a stem cell found in the bone marrow. They give way to RBC's through a process known as haematopoiesis. All of this is controlled by erythropoietin, a hormone mainly made in the kidneys. An adult RBC looses its nucleus to make room for the oxygen it will carry through the blood vessels. An RBC lasts for about 120 days. At the end of their life span, their membranes fall off and they are consumed by phagocytic cells from the spleen, bone marrow and liver.

The body knows to increase production of RBC's when oxygen levels drop slightly.
