Saliva has what in it to help with digestion?
Mucins, electrolytes, antibodies, enzymes
What enzymes are in saliva? What do they do?
Salivary amylase- begins chemical digestion of complex carbohydrates
lingual lipase- begins chemical digestion of triglcerides

what is the esophagus?
A muscular tube leading from the mouth to the stomach. DOES NOT contribute to digestion on its own (all about propulsion/motility)
What is the esophagus involved in?
movement of food mass - involves waves of muscular contraction called peristalsis

esophagus
How is the entrance and exit of stuff regulated by the esophagus?
Sphincters
Upper esophageal sphincter
Lower esophageal sphincter
