The human body has an organ A which acts as a double pump. The oxygenated blood coming from the lungs through blood vessel B enters the upper left chamber C of the double pump. When chamber C contracts, then blood goes into the lower left chamber D. The contraction of chamber D forces the blood to go into a blood vessel E which supplies oxygenated blood to all the organs of the body (except the lungs). The deoxygenated blood coming out of the body organs is taken by a blood vessel F to the right upper chamber G of the pumping organ. Contraction of chamber G forces the deoxygenated blood into the right lower chamber H. And finally, the contraction of chamber H sends the deoxygenated blood into the lungs through blood vessel I.
