Red blood cells, also called erythrocytes, are the most abundant cell type in the blood. Other major blood components include plasma, white blood cells, and platelets. The primary function of red blood cells is to transport oxygen to body cells and deliver carbon dioxide to the lungs.

A red blood cell has what is known as a biconcave shape. Both sides of the cell's surface curve inward like the interior of a sphere. This shape aids in a red blood cell's ability to maneuver through tiny blood vessels to deliver oxygen to organs and tissues.

Red blood cells are also important in determining human blood type. Blood type is determined by the presence or absence of certain identifiers on the surface of red blood cells. These identifiers, also called antigens, help the body's immune system to recognize its own red blood cell type.
