• All of the listed responses are correct.

The nose serves all of the following functions EXCEPT

• warming and humidifying the air

• as a passageway for air movement

• as the direct intiator of the cough reflex

Most inspired particles such as dust fail to reach the lungs because of the

• ciliated mucous lining in the nose

• action of the epiglottis

• abundant blood supply to nasal mucosal

• porous structure of turbinate bones

What structure prevents food and liquids from entering the trachea?

• laryngeal prominence

• glottis

• vestibular folds

• epiglottis

The larynx contains

• the thyroid cartilage

• lateral cartilage ridges called false vocal cords

• an upper par of avascular mucosal folds called true vocal folds

• a cricoid carilage also called the Adam's apple

Which of the following provide the greatest surface area for gas exchange?

• alveoli ducts

• respiratory bronchioles

• terminal bronchioles

• alveoli

Tracheal obstruction is life threatening.

• true

• False

Emphysema can result in an

• increased level of carbaminohemoglobin

• increased level of deoxhemoglobin

• increased likelihood of the skin of Caucasians developing a slighty blue coloration

• All of the above
