Heart Structure and Function

Learn how the chambers of the heart contract and relax in synchrony to push blood through the pulmonary and systemic loops of the circulatory system in this video segment. Watch as the heart pumps oxygen-depleted blood to the lungs, where red blood cells acquire oxygen, before travelling back to the heart and then on to the rest of the body.
