Answer 2

$\underline{\underline{\boxed{\colorbox{Black}{HeyMate}}}}}}$

IRV:--

➡Inspiratory Reserve Volume (IRV): Total lung capacity minus the volume of air in the lung at the end of a normal inspiration.

❇ $\textcolor{Blue}{\colorbox{green}{It is the maximum volume of air that can be inhaled after a normal inspiration.}}$

❇It is about 2500 – 3500 mL in the human lungs.

ERV:--

➡Expiratory Reserve Volume (ERV):

❇This is the difference between the volume of air left in the lung at the conclusion of normal expiration versus at the conclusion of maximal expiration.

❇It is the maximum volume of air that can be exhaled after a normal expiration.

❇ It is about 1000 – 1100 mL in the human lungs.
