Question
Chapter 9, Problem 9RQ
Summary Introduction
Introduction:
The peripheral chemoreceptors are oxygen sensitive cells that respond to the decreased levels of oxygen in the arterial blood. There are some other factors, apart from oxygen levels, which facilitate the stimulation of peripheral chemoreceptors.
