Summary Introduction

To explain: The different reflexes that alter breathing rate and depth.

Concept introduction: Reflexes are rapid, preprogrammed, and involuntary responses of a gland or muscle to a stimulus. The breathing rate and depth are either altered through reflexes or by the cerebrum. On detection of stimuli, receptors relay sensory input to the respiratory center, which in turn alter breathing rate and depth.
