As mammals our aerobic metabolic system requires oxygen for us to sustain life. The organ that transports oxygen from the environment into the body where it is needed, are the lungs. Oxygen is transported through cellular respiration from the lungs to tissues and organs. Between 2,100 to 2,400 gallons of air is breathed to fuel 2,400 gallons of blood that is pumped into the heart. Respiration is controlled by the medulla oblongata, which deals with the autonomic function of breathing. This characteristic allows one to breathe without having to think about the process but can also be overridden and controlled in certain situations. As a result of respiration, carbon dioxide is produced where it is removed for oxygen to be restored. The purpose
