What is the life cycle of red blood cells?

Posted by Keshav Jain on



All blood cells are made in red bone marrow. Almost all the bones of young people contain red bone marrow. For adults, it is only found in the skull, ribs, shoulder blades, hips, and the ends of long bones.



Cell cycle



A red blood cell lives for up to 120 days before being swallowed by a type of white blood cell, called a macrophage, in the liver or spleen.



New blood cells are made by red bone marrow. A new red blood cell is released into the blood stream. The worn-out red cell is digested by a macrophage. Waste from the blood cell is removed. Useful parts of the old blood cell are recycled.
