Ch 15--Digestive system Flashcards
Digestion
Process of breaking down food.
Absorption
Once food is broken down the molecules move through the wall of the digestive tract into the blood and lymph for distribution
6 regions of the digestive tract
Oral cavity (mouth)
Pharynx (throat)
Esophagus

Accessory organs

Food enters the stomach
Through the lower esophageal sphincter and leaves the through pyloric sphincter.
