Overview of the cardiovascular system & the heart ch 22a overview of the cardiovascular system. The heart is the center of the cardiovascular system. Beats ~72 times per min on average. Arteries & veins entering & leaving the heart are called great vessels. Arteries carry blood away from the heart. Veins carry blood back to the heart. The heart is two side-by-side pumps that work at the same rate & pump the same volume of blood. Right heart: directs blood to the lungs gas exchange. Left heart: directs blood to body tissues gas, nutrients, waste delivery. Heart valves: unidirectional blood flow pulmonary & systemic circulations. The cardiovascular system consists of 2 circulations: pulmonary circulation. Right heart pumps deoxygenated blood through pulmonary arteries lungs. After gas exchange, pulmonary veins carry blood left heart: systemic circulation. Left heart pumps oxygenated blood through systemic arteries body"s cells.
