vital capacity

Biology
  • The total amount of air that can be exhaled after maximum inspiration. The vital capacity of an average human is typically 4.5–5 litres; in trained male athletes it can be 6 litres or more. However, some air always remains in the lungs (see residual volume). Hence, the total lung capacity is the sum of vital capacity and residual volume.
