Red blood cells are called erythrocytes and deliver oxygen to the tissues and return carbon dixoide from the tissues to the lungs. They are released from the bone marrow with a life span of 120 days. Unlike most cells of the body, mature red cells do not contain a nucleus.

Actually, this question is best answered by turning it around and asking why human red blood cells don't have a nucleus. The reason that human (acutally all mammalian)mature red blood cells lack a nucleus appears to be so that the red blood cell has room for more hemoglobin and therefore can carry more oxygen per cell.

Red blood cells are made in the bone marrow. They start out with a nucleus, like other cells, but when they fill up with hemoglobin the nucleus is squished smaller and smaller until it disappears. With no nucleus, red blood cells are fragile and live only about 120 days.

Human red blood cells take on average 20 seconds to complete one cycle of circulation.[1] [22] [2] As red blood cells contain no nucleus, protein biosynthesis is currently assumed to be absent in ... Furthermore, red blood cells do not have an insulin receptor and thus their glucose uptake is not regulated by insulin.
