Question

Distinguish between Inspiratory Reserve Volume (IRV) and Expiratory Reserve Volume (ERV).​

Answer 1

Answer:-

Difference between the IRV(Inspiratory Reserve Volume) and ERV(Expiratory Reserve Volume) are given below:

$\:$

IRV:

• Total lung capacity minus the volume of air in the lung at the end of a normal inspiration. This means that we have a reserve volume that we can tap into as tidal volume increases with exercise or activity.
• IRV is about 2500 – 3500 mL in the human lungs.

ERV:

• Difference between the volume of air left in the lung at the conclusion of normal expiration versus at the conclusion of maximal expiration. That means that we have a "reserve" volume which we can tap into when our tidal volume increases with exercise or activity.
• ERV is about 1000 – 1500 mL in the human lungs.
