Countercurrent exchange relies on blood vessels carrying blood to the extremities lying close to blood vessels returning to the body core. As the blood returns to the body core, heat passes from the blood in the vessels leading to the extremities. In this way heat is exchanged within the body and not between the body and the external environment.
