Disc-shaped cells {red blood cell}| {erythrocyte} contain hemoglobin and have no nucleus.
purpose
Hemoglobin transports oxygen and carbon dioxide.
metabolism
In capillaries, carbonic anhydrase converts carbon dioxide to carbonic acid, for hemoglobin transport. Lungs convert carbonic acid to carbon dioxide and breathe carbon dioxide from body.
amount
Blood-oxygen decrease increases red-blood-cell production. Spleen and liver phagocytize red blood cells. Diarrhea can cause polycythemia.
types
Fetuses have a different hemoglobin type. Sickle cell anemia has red blood cells with curved shapes.
