Chapter 9, Problem 1CAQ1

Summary Introduction

To review:

Whether the statement, “As an individual ascends a mountain, both the barometric pressure and atmospheric ${\text{P}}_{{\text{O}}_{\text{2}}}$ decrease,” is true or false.

Introduction:

Barometric pressure is also known as the atmospheric pressure. The central and peripheral chemoreceptors regulate the ventilatory pattern. The moment an individual ascends to a higher altitude, a sequence of events take place to regulate the breathing pattern. Initially, the peripheral chemoreceptors are stimulated, then the central chemoreceptors are readjusted.
