What is the role of the epiglottis?

Back

The epiglottis covers the laryngeal inlet during swallowing to prevent food from entering the lower respiratory passages.

Front

What volumes make up the inspiratory capacity?

Back

Inspiratory capacity is the sum of tidal volume (TV) and inspiratory reserve volume (IRV).

Front

Back

The opening is located in the nasopharynx.

Front

What is tidal volume (TV)?

Back

Front

What is residual volume (RV)?

Back

Residual volume is the amount of air remaining in the lungs after a forced exhalation.

Front

What is the glottis?
