Quizplus · Accepted Answer

Pulmonary ventilation specifically refers to the process of air moving into and out of the lungs, whereas the other options refer to different aspects of respiration. External respiration involves the exchange of gases between the lungs and the bloodstream, while internal respiration refers to the exchange of gases between the bloodstream and the body's tissues. Gas exchange is a general term that could refer to any type of exchange of gases, including those that occur during respiration but also those that occur in other contexts (e.g. in the bloodstream or in other organs).
