use of oxygen within mitochondria to generate ATP by oxidative phosphorylation and the production of carbon dioxide as a waste product. External respiration is the exchange of oxygen and carbon dioxide between the

air passages in the head and neck. Air enters the nasal
cavity and/or oral cavity, both of which lead to the
pharynx — a muscular tube that serves as a common
passageway for both air and food. After the pharynx, the
passageways for food and air diverge. Go to the next screen: The Wt includes
