Question

Chapter 53, Problem 1.8A

Summary Introduction

To fill:

The correct term in the given blank.

Introduction:

Breathing is controlled from regions of the brainstem respiratory centers, which control both inspiration and expiration. These areas initiate and regulate nerve impulses that travel to various muscles of breathing. Forced expiration involves the exhalation of maximum amount of air possible from the lungs into the atmosphere, which rids the body of carbon dioxide.
