Final answer:
The components of a normal spirogram are vital capacity (VC), inspiratory capacity (IC), total lung capacity (TLC), functional residual capacity (FRC), and residual volume (RV).
Step-by-step explanation:
Vital capacity (VC) is the amount of air a person can move into or out of their lungs, and is the sum of all of the volumes except residual volume. Inspiratory capacity (IC) is the maximum amount of air that can be inhaled past a normal tidal expiration, and is the sum of the tidal volume and inspiratory reserve volume. Total lung capacity (TLC) represents the total amount of air a person can hold in the lungs after a forceful inhalation, and is the sum of all of the lung volumes. Functional residual capacity (FRC) is the amount of air that remains in the lung after a normal tidal expiration, and is the sum of expiratory reserve volume and residual volume. Residual volume (RV) is the amount of air that is left in the lungs after a maximal exhalation.
