Answer to Question 1

Hypercapnia refers to a condition of elevated partial pressure of carbon dioxide. This rise is detected by chemoreceptors in the aortic and carotid bodies and powerfully stimulates ventilation through effects on pontine nuclei. Hypercapnia results from increased production as during exercise or reduced elimination as in reduced alveolar ventilation.

Answer to Question 2

C
