Exam 36: Ventilation

Which of the following constitutes total lung volume?

Standard atmospheric pressure is usually about 760 mm Hg.

Because residual volume cannot be voluntarily exhaled, it is not included as part of vital capacity.

Anatomical dead space contains air that does not ventilate the alveoli.

The tendency of the thorax and lungs to return to the preinspiration volume is called:

Internal respiration can be defined as:

External respiration can be defined as:

Identify and describe four nonrespiratory breathing reflexes.

The diving reflex is related to the effects of hydrostatic pressure on the body.

Match each pulmonary volume with its corresponding description or definition. -Largest additional volume of air that can be expired after tidal volume

Match each type of breathing with its corresponding definition. -Normal, quiet breathing

A primary function of the respiratory system is to supply tissue with adequate oxygen and to remove carbon dioxide.

Match each pulmonary volume with its corresponding description or definition. -Amount of air that cannot be forcibly expired and is trapped in the lung

The contraction of the abdominal muscles and the sternocleidomastoid allow much more air to leave the lungs than does the simple recoil of the lungs.

The cerebrospinal fluid (CSF) is much more influenced by carbon dioxide in the blood because there is no buffering system in the CSF as there is in the blood.

Which type of breathing is characterized by repeated sequences of deep gasps and apnea, and is usually seen in people with increased intracranial pressure?

Match each type of breathing with its corresponding definition. -Decrease in pulmonary ventilation that results in elevated blood levels of carbon dioxide

Chemoreceptors can be found in both the carotid bodies and the aorta.

Hypoventilation is characterized by low levels of carbon dioxide.

Although the respiratory system is responsible for ventilation, the circulatory system is responsible for perfusion.
