Document Summary
Once materials are in blood, the cardio distributes them. Cardio consists of heart, blood vessels, and blood. Arteries carry blood away from the heart and veins carry blood to the heart. Heart is divided by a central wall septum into left and right valves. Each half fxns as an independent pump consisting of an atrium, and a ventricle. Atrium receives blood returning to the heart from the blood vessels. Ventricle pumps blood out into the blood vessels. Right side of the heart receives blood from tissues and sends it to the lungs deoxygenated blood. Right atrium, blood flows into right ventricle and pumped through pulmonary arteries to the lungs. Left side receives newly oxygenated blood from the lungs and pumps it to the tissues. From the lungs, blood travels to left side through pulmonary veins. Blood vessels that go from right ventricle to the lungs and back to left atrium known as pulmonary circulation.
