Respiratory System Flashcard

Front

What is the function of the paranasal sinuses?

Back

The paranasal sinuses produce mucus, resonate speech, and lighten the skull. They do NOT keep airways open.

Front

What lung volume is most applicable for blowing out candles?

Back

Expiratory reserve volume is the lung volume most applicable for blowing out candles.

Front

Describe the path of carbon dioxide as it leaves the capillaries and exits through the respiratory system.

Back

The path of carbon dioxide is: alveoli, bronchioles, bronchi, trachea, larynx, pharynx, mouth/nose.

Front

How do ciliated cells in the respiratory mucosa function?

Back

Ciliated cells propel foreign particles inferiorly from the nasal cavity and superiorly from the trachea.

Front

What is not part of vital lung capacity?

Back

Residual volume is not part of vital lung capacity.

Front

Define tidal volume.

Back

Tidal volume is the amount of air inhaled or exhaled during normal breathing.

Front

What is inspiratory reserve volume?

Back

Inspiratory reserve volume is the maximum amount of air that can be inhaled after a normal inhalation.

Front

What is expiratory reserve volume?

Back

Expiratory reserve volume is the maximum amount of air that can be exhaled after a normal exhalation.

Front

What is residual volume?

Back

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

Front

What role do alveoli play in the respiratory system?

Back

Alveoli are the sites of gas exchange in the lungs, allowing oxygen to enter the blood and carbon dioxide to be expelled.
