Finally, the cell becomes a full mature red blood cell and enters the blood, ready to transport oxygen throughout the body. The life of a red blood cell is short due to its lack of nucleus; human red blood cells only survive for about days.

When red blood cells are old or damage, they are ready to be eliminated from the bloodstream. Red blood cell removal is controlled by specialized cells called macrophages in the spleen part of the lymphatic system and the liver.

The spleen disposes of worn-out red blood cells and controls the amount of blood cells at work in the body. Additionally, the liver recycles iron from damaged red blood cells. Together, the macrophages in the spleen and liver remove old red blood cells from the body. Red blood cell count can also be reduced by certain drug interactions or nutritional deficiencies iron, copper, vitamin B-6, vitamin B, or folate.

While some red blood cell diseases can be caused by illnesses or nutritional deficiencies, others are inherited. Diseases involving red blood cells include anemia low red blood cell count or low hemoglobin , thalassemia inherited blood disorders , and polycythemia vera or other blood cancers.

Learn more about the different components that can be obtained from a whole blood donation. Other times, it is done during the donation itself, using a process called apheresis. Some donors say that this leaves them feeling more hydrated than giving a whole blood donation. Red cells have a shelf life of up to 42 days, depending on the type of anticoagulant used when they are stored.
