Question

Quizplus · Accepted Answer

The rate and depth of breathing increase in an effort to increase oxygen availability accompanied by an increase in the release of oxygen from hemoglobin.
Bronchodilation occurs,not constriction.
Dyspnea is not a compensatory mechanism but a side effect of the body's attempt to increase oxygen.
The respiratory system does not activate the renin-angiotensin response; the kidneys are involved.
