What Are Convection Currents?

Our bodies also make use of convection currents to help regulate body temperature. The internal organs of humans generate a lot of heat and it is through the blood circulatory system that this heat energy is expelled.

As blood is channeled through the organs and deep tissues of the body, it eventually finds its way through vessels like capillaries close to the skin. The heat is then transferred to the air and water that flows over the skin. This flow of blood toward the skin to release heat is an example of forced convection driven by the heart and supported by the cardiovascular system.
