Quizplus · Accepted Answer

Dead-air space refers to the air that remains in the airways (trachea, bronchi, bronchioles) during each breathing cycle and is not available for gas exchange in the alveoli. The residual volume refers to the amount of air that remains in the lungs after maximal exhalation, while the functional reserve volume refers to the amount of air that can be voluntarily exhaled after a normal exhalation.
