The volume of air that can be exhaled after a normal tidal volume exhalation is the
IRV
FRC
FVC
ERV

Introduction:
The volume that remains in the lungs and the volume which moves in and out of the lungs are crucial in cardiopulmonary physiology. There are two major categories in which the total amount of air in the lungs can be divided, namely lung capacity and lung volume. There are four different types of lung volumes, namely- inspiratory reserve, tidal, expiratory reserve, and residual volume.
Answer to Problem 1RQ
Correct answer:
The volume of air that can be exhaled after the normal tidal volume exhalation is known as expiratory reserve volume (ERV).
Explanation of Solution
Justification for the correct answer:
Option (d) is given as ERV. This option is correct as the normal amount of air that moves in and out of the lungs during normal breathing is known as tidal volume. The amount of air that can be forcefully exhaled is known as expiratory reserve volume (ERV). Hence, option (d) is correct answer.
Justification for the incorrect answers:
Option (a) is given as IRV (inspiratory reserve volume). This is false as the inspiratory reserve volume is the amount of air that can be forcefully inhaled after tidal volume. So, it is an incorrect option.
Option (b) is given as FRC (functional reserve capacity). This is false as the functional reserve capacity is the amount of air that remains in the lungs after normal expiration. So, it is an incorrect option.
Option (c) is given as FVC (forced vital capacity). This is false as the forced vital capacity is the maximal effort that the body can exert to exhale as much as possible. So, it is an incorrect option.
Hence, options (a), (b), and (c) are incorrect.
Thus, it can be concluded that the amount of air that can be normally exhaled is tidal volume and the volume that can be exhaled after tidal volume is expiratory reserve volume.

Thank youarrow_forwardMolecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold.
