Blood is pumped from veins of the systemic circuit into the right atrium of the heart, then into the right ventricle. Blood then enters the pulmonary circuit, and is oxygenated by the lungs. From the pulmonary circuit, blood re-enters the heart through the left atrium.Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium. ... As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs, where it is oxygenatedThe purpose of the Circulatory System is to deliver oxygen and nutrients to all the cells in the body. The circulatory consists of the heart and all the bood vessels in the body (arteries, veins and capillaries). Arteries carry blood away from the heart. Veins carry blood to the heart. The smallest blood vessels are the capillaries and they deliver the blood and oxygen to the cells. The blood vessels is said to resemble the branches of a tree with the main artery being the aorta which leaves the heart. The aorta then branches into smaller arteries which then branch into capillaries.
