circulation meaning

noun circu-lation (of the blood ) movement of bloodaround the body from the heart through the ar- teries to the capillaries and back to the heartthrough the veins She has poor circulationin her legs.Rub your hands to get the circu- lation going.COMMENT: Blood circulates around the body carrying oxygen from the lungs and nutrients from the liver through the arteries and capillar- ies to the tissues. The capillaries exchange the oxygen for waste matter such as carbon dioxide which is taken back to the lungs to be expelled. At the same time the blood obtains more oxygen in the lungs to be taken to the tissues. The circulation pattern is as follows: blood returns through the veins to the right atrium of the heart. From there it is pumped through the right ventricle into the pulmonary artery and then into the lungs. From the lungs it returns through the pulmonary veins to the left atrium of the heart and is pumped from there through the left ventricle into the aorta and from the aorta into the other arteries.circulatory
