Q. Spirometer directly measures

NTA AbhyasNTA Abhyas 2020

Solution:

Spirometer: - It is the apparatus that is used to measure the volume of air inspired and expired by the lungs.
1. Residual volume: - The volume of air that remains in the lungs even after forceful expiration.
2. Vital capacity: - The maximum volume of air that a person can breathe in after a forceful expiration.
3. Functional residual capacity: - The volume of air that will remain in the lungs after a normal expiration.
4. Total lung capacity:- The total volume of air present in the lungs and in the respiratory passage after a maximum inspiration.
So, the answer is option 2, which is vital capacity.
