A person with a tidal volume of 450 mL (millilitres), a vital capacity of 4000 mL, and a residual volume of 1000 mL would have a potential total lung capacity of ________.
A) 1450 mL
B) 4000 mL
C) 4450 mL
D) 5000 mL

Question

Quizplus · Accepted Answer

The total lung capacity is equal to the sum of the vital capacity and residual volume. Therefore, potential total lung capacity = vital capacity + residual volume = 4000 mL + 1000 mL = 5000 mL.
