The delivery of this blood to the alveoli is referred to as pulmonary perfusion. Oxygenation is the process where unoxygenated blood receives oxygen in the lungs. Expiration is the act of exhaling to rid the body of excess carbon dioxide. Inhalation is the act of inhaling or taking in air to replace oxygen from the air.
