In animals with lungs —amphibians, reptiles, birds, and mammals—the heart shows various stages of evolution from a single to a double pump that circulates blood (1) to the lungs and (2) to the body as a whole. In humans and other mammals and in birds, the heart is a four-chambered double pump that is the centre of the circulatory system.
