NEET · BiologyEasy
What is the volume of air that remains in the lungs after a forcible expiration?
- A.Tidal volume
- B.Inspiratory reserve volume
- C.Residual volume
- D.Vital capacity
Show correct answer & step-by-step solution
Correct answer: C — Residual volume
Solution
- Residual volume is defined as the volume of air remaining in the lungs after a forced expiration.
- This volume prevents the lungs from collapsing.
- It cannot be measured by a simple spirometer.
- Hence the answer is (C).
