Document Summary
Heart sites in your chest cavity between your lungs. The four principle functions of the cardiovascular system are: It transports oxygen and nutrients to all the cells of the body. It transports carbon dioxide and waste from all cells. It transports and distributed hormones and other substances within the body. The heart essentially consists of two side-by-side pumps: the right atrium and ventricle, which pumps blood to the lungs, the left atrium and ventricle, which pumps blood to the rest of the body. Superior vena cava: delivers blood to the heart from the head and upper limbs. Pulmonary artery: blood leaving the right ventricle travels to the lungs through the pulmonary artery. Aorta: blood leaving the left ventricle travels through the aorta and is distributed to the entire body. Right atrium: receives blood from the entire body. This blood is low in oxygen and high in carbon dioxide.
