Quizplus · Accepted Answer

This statement is false. The 500 ml of air that is inspired only partially enters the alveoli during a single breath. While some air reaches the alveoli, some of it remains in the conducting airways and does not participate in gas exchange. In addition, the residual volume of air in the lungs after exhalation prevents complete emptying of the lungs during normal breathing.
