Mr. Smith exhales normally; then, using forced expiration, he exhales as much air as possible. The volume of air still remaining in his lungs is called

• expiratory reserve volume.

• inspiratory reserve volume.

• residual volume.

• tidal volume.

• vital capacity.

Carbon dioxide is primarily transported in the blood

• bound to hemoglobin.

• bound to albumin.

• dissolved in the plasma.

• as part of the bicarbonate ion.

• none of these.

The difference between minute ventilation and alveolar ventilation is that minute ventilation includes…

• A. volume of anatomic dead space

• B. volume in respiratory zone

• C. volume in alveoli.

• D. all of these.

• E. none of these.

When central chemoreceptors detect an increase in the pH of the cerebrospinal fluid:

• cerebellar respiratory centers trigger an increase in rate and depth (volume) of breathing.

• medulla and pons trigger a decrease in rate and depth (volume) of breathing.

• the cerebrum trigger a decrease in rate and depth (volume) of breathing.

• the occipital lobe causes the diaphragm to increase contraction rate.

• the corpus callosum sends signals to the lungs.
