Lecture 26:  Respiratory System - Control

Sherwood: Chapter 11

Objective:  To understand how the respiratory center in the brain stem establishs a rhythmic breathing pattern.  What controls the magnitude of ventilation is the carbon dioxide-generated hydrogen ion concentration in the brain extracellular fluid.

1.  Respiratory control centers
        a.  medullary
        b.  apneustic and pneumotaxic
        c.  dorsal
2.  Peripheral chemoreceptors
3.  Central chemoreceptors
