Document Summary
Present in blood continuously available to any cell that. Composed of the heart, blood vessels, and the cells and plasma of the blood. As blood moves through the cardio system, valves in the heart and veins ensure blood flow in 1 direction. The heart is divided by a central wall (septum), into the right and left halves. Each half functions as an independent pump that is composed of an atrium and a ventricle. The atrium receives blood returned to the heard from blood vessels and the ventricles pump blood back into the vessels. The right side receives blood, and sends it to the lungs for oxygenation, while the left side receives oxygenated blood and sends it to the rest of the body. Blood vessels from the right ventricle to the lungs and back to the left atrium (pulmonary circulation) The aorta branches into a series of smaller and smaller arteries that finally lead to networks of capillaries.
