The four respiratory events in the human body are ventilation, external respiration, transport of gases, and internal respiration. Ventilation refers to the movement of air in and out of the lungs. External respiration involves the exchange of oxygen and carbon dioxide between the alveoli and the blood. Transport of gases occurs as oxygen and carbon dioxide are carried in the bloodstream, while internal respiration is the exchange of gases between the blood and body tissues.
