Starting from the left atrium, state the order in which the blood flows through including lungs, valves, veins and arteries.
First, oxygenated blood is pumped from the left atrium, through the valve and into the left . Then, the blood gets pumped through the valve and through the where it gets transported to the rest of the body. After it has been through the body and the oxygen has been used, the deoxygenated blood travels through the to the right . The right atrium then contracts, pushing the blood through the valve and into the where it contracts to and forces the blood through the valve into the artery to the lungs to be oxygenated. The then oxygenated blood gets pushed back to the heart via the vein back into the left atrium.
