Description
Colored scanning electron micrograph (SEM) of capillaries (red) carrying blood to muscle fibres (brown). The capillary network supplies the muscle with oxygen and nutrients, which it uses to create energy by respiration. The blood also takes away the waste product of respiration, carbon dioxide. The capillaries are so fine that a red blood cell (erythrocyte) can only just pass through. Enlargement 6900x.
