What is total capacity of lungs?

Introduction. Lung capacity or total lung capacity (TLC) is the volume of air in the lungs upon the maximum effort of inspiration. Among healthy adults, the average lung capacity is about 6 liters. Age, gender, body composition, and ethnicity are factors affecting the different ranges of lung capacity among individuals

Does the volume of air you inhale always equal the volume you exhale?

In humans, when each breath is completed, the lung still contains a volume of air, called the functional residual capacity (approximately 2200 mL in humans). Each inhalation adds from 500 mL of additional air for normal (resting) breathing. Each exhalation removes approximately the same volume as was inhaled.
