The heart sits on the main muscle of breathing (the diaphragm), which is found beneath the lungs. The most important function of the cardiovascular system (the heart and blood vessels together) is to keep blood flowing through capillaries. This allows capillary exchange to take place. Capillary exchange is the process of nutrients passing into the body's cells and waste products passing out. What do the heart and blood vessels do? The heart's main function is to pump blood around the body. Blood carries nutrients and waste products and is vital to life. One of the essential nutrients found in blood is oxygen. The right side of the heart receives blood lacking oxygen (deoxygenated blood) from the body. After passing through the right atrium and right ventricle this blood is pumped to the lungs. Here blood picks up oxygen and loses another gas called carbon dioxide. largest artery in the body; receives oxygenated blood, at pressure, directly from the left ventricle and transports it to the body superior vena cava large vein that collects deoxygenated blood from the head and arms and returns it to the right atrium of the heart inferior vena cava large vein that collects deoxygenated blood from the abdomen and lower body and returns it to the right atrium of the heart pulmonary artery receives deoxygenated blood, at pressure, from the right ventricle and takes it to the lungs pulmonary vein carries oxygenated blood from the lungs to the left atrium of the heart The venae cavae (from the Latin for hollow veins, singular vena cava) are two large veins (venous trunks) that return deoxygenated blood from the body into the heart. In humans there are the superior vena cava and the inferior vena cava, and both empty into the right atrium. superior vena cava. large vein that collects deoxygenated blood from the head and arms and returns it to the right atrium of the heart. inferior vena cava. large vein that collects deoxygenated blood from the abdomen and lower body and returns it to the right atrium of the heart. These are the first arteries to branch off the large artery (aorta) which takes blood to the body from the left ventricle. 1  The right coronary artery mainly supplies the muscle of the right ventricle. 2  The left coronary artery quickly splits into two and supplies the rest of the heart muscle. The blood supply to the heart. 1  The right coronary artery mainly supplies the muscle of the right ventricle. 2  The left coronary artery quickly splits into two and supplies the rest of the heart muscle. 3  The main coronary arteries divide into many smaller branches to supply all the heart muscle. What are the heart and blood vessels? The heart is a muscular pump that pushes blood through blood vessels around the body. The heart beats continuously, pumping the equivalent of more than 14,000 litres of blood every day. Blood vessels form the living system of tubes that carry blood both to and from the heart.
Yes, the blood vessels that return deoxygenated blood to the heart.
