Question

practice it
what is total lung capacity?
the amount of air in the lungs during maximum inhalation
the volume of air that is inhaled and exhaled during normal breathing
the amount of air left in the lungs after exhaling
the rate at which air is exchanged in the lungs
maximum amount of air that the lungs can hold

Explanation:

Total lung capacity (TLC) is defined as the maximum amount of air that the lungs can hold. It is the sum of all lung volumes (tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume).

• The amount of air in the lungs during maximum inhalation is not the same as TLC.
• The volume of air inhaled and exhaled during normal breathing is tidal volume.
• The amount of air left in the lungs after exhaling is residual volume.
• The rate at which air is exchanged in the lungs is not related to TLC.

Answer:

Maximum amount of air that the lungs can hold
