Part two of a three part video discussing the physiology of respiration. The ultimate goal of respiration is to transport oxygen to the mitochondria of the cells. This involves getting oxygen into the lungs (ventilation), getting the oxygen into the blood (external respiration), transporting the oxygen through the blood (transport), moving the oxygen out of the blood into the tissue (internal respiration) and then using the oxygen to make the body's energy molecule, ATP (cellular respiration)
