If stem cells mature into erythrocytes (red blood cells), they will become specialized for oxygen transport in the body. Erythrocytes are responsible for carrying oxygen from the lungs to the rest of the tissues and organs, as well as removing carbon dioxide waste. They have a unique biconcave shape and lack a nucleus to maximize their capacity for oxygen-carrying.
Nothing as erythrocytes (i.e. red blood cells) are never"pumped into cells". They stay inside the blood vessels, circulating around and around.
Normally if they get lucky just 2 weeks but if not at least a month :)
