The flap of elastic cartilage that protects food from entering the larynx when swallowing:

The opening between the vocal cords is called the:

Following the removal of the larynx, a person would be unable to:

What is the role of mucus in the nasal cavity:

The respiratory conducting passageways perform all of the following functions except:

The conducting passageways of the respiratory system include all the following structures except:

The walls of the alveoli are composed mainly of:

Exchange of both oxygen and carbon dioxide through the respiratory membrane occurs by:

Air moving in and out of the lungs is called:

The gas exchange that occurs between blood and tissue cells at systemic capillaries is called:

An emotionally-induced response during which air movement is similar to crying is:

A very deep inspiration that ventilates all alveoli:

Most carbon dioxide is transported within blood plasma as:

Oxygen binds with hemoglobin in the blood to form:

The bluish cast that results from inadequate oxygenation of the skin and mucosa:

Cessation of breathing is called:

Which of the following is NOT a factor influencing respiratory rate and depth:

The molecule that prevents lung collapse by lowering the surface tension of the water film lining each alveolar sac:

Which of the following is NOT true of cystic fibrosis:

The homeostatic imbalance associated with the death of many full-term newborn infants:

A condition in which the walls of the alveoli enlarge and become damaged leading to breathlessness:

Inflammation of the nasal mucosa caused by cold viruses and various allergens:

Genetic defect resulting from the failure of the bones forming the palate to fuse medially making breathing difficult as well as chewing and speaking:

Infection involving the passageways connecting the sinuses to the nasal cavity (blocked with mucus or infectious matter):

Collapsed lung (can result from a chest wound or rupture of the visceral pleura):

Condition that results when there is inadequate oxygen delivery to body tissues (may be caused by anemia, pulmonary disease, impaired or blocked circulation):

Condition caused by chronically inflamed, hypersensitive bronichial passages that respond to many irritants with dyspnea, coughing, and wheezing:

Condition by which the pharyngeal tonsils become inflamed and swollen obstructing the nasopharynx forcing the person to breathe through the mouth:

Mucosa of the lower respiratory passageways becomes severely inflamed producing excessive mucus. Mucus impairs ventilation and gas exchange and may lead to pneumonia:
