The heart is a muscular pump that pushes blood through blood vessels around the body. Essential to life, the heart beats continuously, pumping the equivalent of more than 14,000 litres of blood every day. Blood vessels form the living system of tubes that carry blood both to and from the heart.
What do blood vessels have to do with the skin regulating body temperature? They are near the surface of the skin, which allows your body heat to be released from the blood and out through the skin. If there is more heat that needs to be released, then there is more blood in the blood vessels.
