Digestive System

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.

What are the functions of the Gi tract   Motility, Secretion, Digestion, Absorption  
What is motility   Movement- starts w/ swallowing  
What is secretion   stats in the mouth w/ saliva (goes through GI) pH in stomach is <1.0 breaks down food. Chime in the stomah when dumped to deuodum neutralizes  
Parasympathetic nervous system is controlled by what nerve   vagus nerve  
What triggers peristalsis   foot streching stomach, increase in pH (when food enters stomach HCL acid is secreted, pleasant smell and hunger  
Sympathetic Nervous System when is it triggered?   conversely inhibits gastrointestinal activity, causes vasoconstriction, and reduces regeneration of epithelial cells
