Here are the essential concepts you must grasp in order to answer the question correctly.
Inspiratory Capacity
Inspiratory capacity (IC) is the maximum amount of air that can be inhaled after a normal expiration. It is calculated as the sum of tidal volume (the amount of air inhaled or exhaled during normal breathing) and inspiratory reserve volume (the additional air that can be inhaled with effort after a normal inhalation). Understanding this concept is crucial for evaluating respiratory function.

Vital Capacity
Vital capacity (VC) is the total amount of air that can be exhaled after a maximum inhalation. It is the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume. This concept is essential for assessing lung health and capacity, as it reflects the maximum volume of air a person can control during breathing.

Tidal Volume
Tidal volume (TV) is the amount of air that is inhaled or exhaled during normal breathing at rest. It is a fundamental component of respiratory physiology and is important for understanding how much air is exchanged in the lungs during typical respiratory cycles. Tidal volume is a key factor in calculating other lung volumes and capacities.
