Exam 36: Ventilation

If the tidal volume of a given individual is 500 ml, then the anatomical dead space is approximately _____ ml.

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

The amount of air that could be forcibly expired after normal expiration is called the functional residual capacity.

Residual volume and minimal volume make up about 5% of vital capacity.

The inspiratory center is located in what part of the nervous system?

Vital capacity is defined as the:

Name and explain the pulmonary volumes and capacities. Which of these increase and decrease as a person moves from normal breathing to forceful inspiration and expiration?

The expiratory center of the medulla seems to be inactive in normal, quiet breathing.

The vital capacity is equal to the sum of the:

The inspiratory capacity is equal to the sum of the tidal volume and the inspiratory reserve volume.

A rise in the carbon dioxide partial pressure is frequently linked to a rise in pH.

Which muscles are used for forced expiration?

As lung compliance decreases, the efficiency of respiration increases.

Which explains the relationship between the gas pressure gradient of the atmosphere and the alveolar air that allows inhalation?

Match each type of breathing with its corresponding definition. -Increased breathing that is regulated to meet an increased demand by the body for oxygen

If the tidal volume were 600 ml, the alveolar ventilation would be about _____ ml.

The pneumotaxic center is located in the pons of the brain.

Dyspnea is often associated with hyperventilation.

A poorly perfused but well-ventilated part of the lung wastes blood.

In maximum inspiration and expiration, the inspiratory and expiratory reserve volumes would change but the residual volume would remain constant.
