The two faces of the disc are not planar, but are closer to each other in the centre than at the edges of the erythrocyte, giving the cell its characteristic biconcave form. Erythrocytes are present in enormous numbers in the blood stream, there normally being between 4,000,000 and 6,000,000 cells in each cubic millimeter of blood.
