Question

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