Definitions:

Pharynx

The muscular tube that connects the mouth and nasal passages with the esophagus.

Tidal Volume

The amount of air that is inhaled or exhaled in a normal breath under resting conditions, important in respiratory physiology.

Inspiratory Capacity

The maximum amount of air that can be inhaled after a normal exhalation, used in assessing lung function.

Inspiratory Reserve Volume

The extra volume of air that can be breathed in beyond a regular breath, adding to the overall lung capacity.
