Blood vessels, SEM

Blood vessels. Coloured scanning electron micrograph (SEM) of a resin cast of blood vessels in the penis. A branching network of fine vessels infiltrates the tissue of the penis, supplying it with blood. Gases and nutrients are exchanged between the blood and surrounding tissue through the permeable walls of capillaries, the smallest blood vessels. The cast was made by injecting resin into the blood vessels. The surrounding tissues were then chemically digested. Magnification: x36 at 6x7cm size.
