Animation of the flow of blood through a blood vessel.
Shown are red blood cells (erythrocytes, red), which transport oxygen, white blood cells (leucocytes, white), part of the immune system, and platelets (thrombocytes, yellow), which are active in blood coagulation (clotting)

Blood vessels from the external wall of the small intestine, coloured scanning electron micrograph (SEM).
This is a cast: the vessels were filled with a resin, which then set. The surrounding tissues were then eaten away chemically, leaving the cast of the vessels. Magnification: x21 when printed 10cm wide.'
