Also known as the cardiovascular system, your heart, blood vessels and blood itself are three essential components the body needs to survive. The circulatory system consists of two circuits that blood travels through; pulmonary and systemic. Exercise affects these systems, causing the heart to pump blood faster around the body, which in turn allows you to exercise for longer!
