Answer 1

Hyperpnea refers to an increased depth and rate of ventilation to meet an increase in oxygen demand during exercise or in diseases affecting the respiratory or digestive tracts.

Step-by-step explanation:

Hyperpnea refers to an increased depth and rate of ventilation to meet an increase in oxygen demand. It is often seen during exercise or in diseases affecting the respiratory or digestive tracts. Hyperpnea does not significantly alter blood oxygen or carbon dioxide levels, but rather increases the depth and rate of ventilation to meet the cellular demand for oxygen.
