Answer to Question 1

ANS: C
Stretch receptors, not carbon dioxide receptors, decrease ventilatory rate and volume when stim-ulated. Baroreceptors regulate blood pressure. Chemoreceptors increase the rate and depth of respiration.

Answer to Question 2

ANS: D
J-receptors (juxtapulmonary capillary receptors) are located near the capillaries in the alveolar septa. They are sensitive to increased pulmonary capillary pressure, which stimulates them to ini-tiate rapid, shallow breathing, hypotension, and bradycardia.
Neither irritant receptors, chemoreceptors, nor stretch receptors respond to increased pulmonary capillary pressure.
