Question
Chapter 16, Problem 13RA
Summary Introduction
To determine:
The location of the inspiratory and expiratory neurons which produce rhythmic control of breathing.
Introduction:
A physical process of exchange of gases between blood and environment inside the lungs is termed as breathing. Breathing involves two steps, namely inspiration and expiration. Inspiration involves inhaling the air with a higher oxygen level, whereas expiration involves releasing the air with a high carbon dioxide level. Breathing is an involuntary action.
