Quizplus · Accepted Answer

Functional residual capacity (FRC) is the volume of air remaining in the lungs after a normal, passive exhalation. This means it is the air that is still present in the lungs after a typical breath out, which helps to prevent lung collapse and maintains a consistent gas exchange in the alveoli.
