Since the red blood cells (erythrocytes) that flow through the capillaries have a diameter of about seven micrometers, they must deform somewhat when they flow through the small blood vessels. This minimizes the … Structure of capillaries | Capillary
Functions of capillaries The function of the capillaries is mainly mass transfer.
