Question

1.)define and give the following volumes in ml : tidal volume. residual volume. inspiratory reserve volume. expiratory reserve volume. vital capacity

Explanation:

Tidal volume is the volume of air inhaled or exhaled during normal breathing. It is approximately 500 ml in an average adult.
Residual volume is the volume of air remaining in the lungs after maximum exhalation. It is about 1200 ml.
Inspiratory reserve volume is the additional volume of air that can be inhaled after a normal inhalation. It is around 3000 ml.
Expiratory reserve volume is the additional volume of air that can be exhaled after a normal exhalation. It is approximately 1100 ml.
Vital capacity is the maximum volume of air that can be exhaled after a maximum inhalation. It is the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume, which is about 4600 ml.

Answer:

Tidal volume: 500 ml.
Residual volume: 1200 ml.
Inspiratory reserve volume: 3000 ml.
Expiratory reserve volume: 1100 ml.
Vital capacity: 4600 ml.
