What is your breathing capacity?

Breathing capacity, or lung capacity, refers to the total amount of air the lungs can hold. It varies from person to person based on factors like age, gender, body composition, and fitness level. Key components include tidal volume (the amount of air inhaled or exhaled in a normal breath), inspiratory reserve volume, expiratory reserve volume, and residual volume. A typical healthy adult has a total lung capacity of about 6 liters.
