Humans, like all mamals breath using their lungs. In the lungs oxygen in the surrounding air is taken in by cells that line the lungs to be used by every organ and tissue in the body. Those same organs and tissues expel carbon-dioxide as a waste product and follows the reverse path from the lungs through bronchial tube to the nose and mouth.
