Blood capillaries are found beneath the epidermis, and are linked to an arteriole and a venule. Arterial shunt vessels may bypass the network in ears, the nose and fingertips.

They send out a series of factors, diffusible proteins that seduce capillaries to grow from the normal circulation into the tumor mass thereby supplying cells in the tumor mass with their much needed nutrients and oxygen.
