Here are the essential concepts you must grasp in order to answer the question correctly.
Functional Residual Capacity (FRC)
Functional Residual Capacity (FRC) is the volume of air remaining in the lungs after a normal tidal expiration. It is a crucial measure in respiratory physiology, reflecting the balance between the forces of lung recoil and chest wall expansion. FRC is important for understanding lung mechanics and gas exchange efficiency.

Tidal Volume (TV)
Tidal Volume (TV) is the amount of air inhaled or exhaled during a normal breath. It is a fundamental component of respiratory function, influencing overall lung volumes and capacities. Understanding TV helps in assessing respiratory health and the efficiency of ventilation.

Lung Volumes and Capacities
Lung volumes and capacities are measurements that describe the different amounts of air the lungs can hold. These include tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. Knowledge of these concepts is essential for interpreting pulmonary function tests and diagnosing respiratory conditions.
