Q.4) Explain “ inspiratery capacity “ and Residual volume “​

Answer 1

Answer:

inspiratery capacity:-

The inspiratory capacity (IC) is the amount of air that can be inhaled after the end of a normal expiration. It is, therefore, the sum of the tidal volume and inspiratory reserve volume. ... It is the sum of the residual volume, expiratory reserve volume, tidal volume, and inspiratory reserve volume.

Residual volume:-

Residual volume (RV) is the volume of air remaining in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled, thus causing the alveoli to remain open at all times. The residual volume remains unchanged regardless of the lung volume at which expiration was started.
