Exam 17: Respiratory System

The two phases of pulmonary ventilation are

Restrictive pulmonary disorders inhibit inspiration.

Which structure does not drain into the nasal cavity?

All of the following are true of the trachea except

One of the reasons for the efficiency of the respiratory system is the thin layer of tissue between the alveoli and the blood capillary. This layer is called the respiratory mucosa.

Internal respiration requires a higher oxygen concentration in the _____ than in the _____.

The lack of surfactant causes both infant and adult respiratory distress syndrome.

The total area for gas exchange in the lung is about 10 m², larger than the entire surface of the body.

Carbon monoxide has a much higher affinity for hemoglobin than does oxygen. Why does this make exposure to carbon dioxide so dangerous?

The amount of air that can be forcibly taken in after normally inhaling is called _____ volume.

Match each of the following terms with its corresponding definition or description. -Structure to which the auditory tubes from the middle ear lead; also called the throat

Internal respiration and cellular respiration refer to the same thing.

If you have exercised very vigorously and are breathing very hard, your tidal volume has increased, but your inspiratory and expiratory reserve volume has decreased.

Dyspnea that is relieved by moving to an upright or sitting position is called apnea.

Which of the following is not part of the upper respiratory tract?

A person with severe respiratory problems may be put on a ventilator and have oxygen supplied through a tube in the trachea. The oxygen must be "bubbled" through water to replace one of the functions of the upper respiratory tract.

Match each of the following terms with its corresponding definition or description. -The exchange of oxygen and carbon dioxide in the lung

Match each of the following terms with its corresponding definition or description. -The sum of tidal volume, expiratory reserve volume, and inspiratory reserve volume

Irritants such as cigarette smoke stimulate mucus production and cilia activity in an effort to help clear the respiratory tract.

The space between the vocal cords is called the epiglottis.
