1

The amount of air expired after maximal expiratory effort.

Forced vital capacity

2

Helps prevents alveolar collapse

Surfactant

3

Injection of a drug that stimulates the carotid bodies would be expected to cause:

A decrease in PCO2 of arterial blood

4

Which of the following is responsible for the movement of O2 from the alveoli into the blood in the pulmonary capillaries?

Passive diffusion

5

Has the greatest effect on the ability of blood to transport oxygen?

Amount of hemoglobin in the blood

6

send out regular bursts of impulses to inspiratory muscles during quiet respiration.

The main respiratory neurons

7

transection of the brainstem at the caudal end of the medulla.

That is where spontaneous respirations cease.

8

Intravenous lactic acid increases ventilation. The receptors responsible for this effect are located in the

Carotid bodies

9

Most of the CO2 transported in the blood is

HCO3-

10

is increased following bronchial smooth muscle contraction.

Airway resistance

11

the amount of air that normally moves into (or out of) the lung with each respiration.

Tidal Volume
