Blood carries useful materials around the body and takes away waste products. Blood helps with communication, by delivering chemical messengers, called hormones, to parts of the body. Blood protects the body from germs, by sealing cuts with thickened, or clotted, blood and by attacking germs with white blood cells. Body temperature can be controlled by directing blood to or away from the skin to warm or cool it.
