 | The Pacemaker of the Heart The Pacemaker of the Heart The pacemaker of the heart, a tiny area of specialized nervous tissue in the right atrium, sets the heart beating about seventy times a minute. Without it the heart would beat only forty times per minute, which is too slow for the body's needs. The pacemaker, or sinuatrial node, regularly sends out nerve impulses which spread through the two atria, causing them to contract. From the atrioventricular node the contraction spreads down special conducting tissue, the bundle of His, causing the ventricles to contract and pump blood out of the heart. |

 | How the Body Works : Inside the Heart Inside the Heart The heart is a muscular pumping organ which beats nonstop to circulate blood around the body. It functions as two halves, each consisting of a holding chamber, or atrium, and a pumping center, or ventricle. After circulating around the body, blood, now deoxygenated, returns to the right atrium through large veins, the superior vena cava and the inferior vena cava. When the atrium is full, blood is forced through the tricuspid valve into the right ventricle. It is then pumped to the lungs through the pulmonary valve into the pulmonary artery. The oxygenated blood returns via the pulmonary veins to the left atrium. After flowing through the mitral valve it is pumped out of the left ventricle into the aorta to return to the general circulation. |
 | How the Body Works : The Continuous Circuit The Continuous Circuit In an adult's body about ten pints of blood are continuously being pumped by the heart through sixty thousand miles of blood vessels. Blood, which has acquired oxygen in the lungs, leaves the heart through the aorta, an inch-wide tube. The aorta branches into large arteries, which take the blood to the neck, head and arms. It then passes down the middle of the body carrying blood to the kidneys, liver, intestines and legs. The large arteries further divide into smaller arterioles and, then finally, into minute capillaries, which surround the body cells. Blood then passes into venules, small veins, and then into larger veins, which feed into the superior vena cava and the inferior vena cava, which return the deoxygenated blood to the heart and then to the lung, where the blood gives up carbon dioxide and acquires a fresh supply of oxygen. |
