THE GREAT VESSELS OF THE HEART (1) The right atrium receives blood from all parts of the body except the lungs. It receives the blood through three veins. The superior vena cava, also known as the anterior vena cava, brings blood form the upper parts of the body, the head, neck and arms. The coronary sinus drains the blood from most of the vessels that supply the walls of the heart with blood. This blood in the right atrium is then squeezed into the ventricle. (2) The right ventricle pumps the blood into the next major vessel, the pulmonary trunk, which splits into the right pulmonary artery and the left pulmonary artery. These carry each the blood to a lung. In the lungs, the blood releases the carbon dioxide it has been carrying and picks up oxygen. The oxygenated blood returns to the heart via four pulmonary veins that empty into the left atrium. The blood is then squeezed into the left ventricle. (3) The left ventricle pumps the blood into the next great vessels, the ascending aorta. From here the aortic blood goes to the coronary arteries which supply wall of the heart with oxygenated blood, the arch of the aorta which send arteries to upper parts of the body and the descending thoracic aorta, which becomes the abdominal aorta. These arteries transport oxygenated blood to all parts of the body. (4) The size of the chambers and the thickness of the chamber walls vary, due to the amount of blood received and the distance this blood must be pumped. The right atrium, which collects blood coming from all parts of the body except the lungs, is slightly larger than the left atrium, which receives only the blood coming from the lungs. The thickness of the chamber walls varies. Ventricles have thick walls, whereas the atria are thin walled.
