Exam 37: Respiratory System Physiology

An average value for vital capacity in healthy young adult males is .

Nervous system centers set the normal resting rate and depth of respiration. Which factors below can alter this normal respiratory rate and depth?

In testing a patient who has tuberculosis, you would expect that the .

The amount of air that can be forcefully exhaled after a normal tidal volume exhalation is called the .

These muscles are active during expiration.

Tidal volume is .

The vital capacity, or maximal amount of air that one can move, is the sum of _.

To measure forced vital capacity (FVC) and forced expiratory volume (FEVT), the subject should .

Carbon dioxide (CO) from tissue cells forms when combined with water. This compound dissociates into H+ and , and participates in an important buffering system in the blood.

After you measure TV and vital capacity, you must also calculate before you can determine total lung capacity.

Inspiration is the time during which .

To compute inspiratory reserve volume (IRV), one would need to know .

Once you have measured TV, IRV, and ERV, you can calculate all the following capacities except .

During inspiration, the volume of the lungs _.

Select the correct sequence of events that occur during inspiration.

Minute respiratory volume can be computed if one knows _ and .

The function of the carbonic acid-bicarbonate buffer system in the blood is to _ .

Vesicular breathing sounds probably result from .

Vesicular breath sounds may be heard .

Hyperventilation causes a in the blood concentration of CO2, and thus the rate of respiration.
