Organs that make up the digestive tract are the mouth‚ esophagus‚ stomach‚ small intestine‚ large intestine—also called the colon—rectum‚ and anus. Inside these hollow organs is a lining called the mucosa. In the mouth‚ stomach‚ and small intestine‚ the mucosa contains tiny

ANATOMY AND PHYSIOLOGY OF THE DIGESTIVE SYSTEM The digestive system is basically a tube running through the body from the mouth to the anus. The organs of the digestive system include the oral cavity (mouth)‚ esophagus‚ stomach‚ small and large intestine and rectum.

6 primary functions of digestive system: 1. Ingestion- food intake 2. Secretion 3. Digestion- mechanical & chemical breakdown of food Mechanical Mastication- first step. Enables mixing with saliva to form bolus to be swallowed. Regulated by CNS. Deglutition Mixing/Churning Peristalsis- movement of muscles within GI tract that facilitates movement of food Chemical- Hydrolysis (using H2O) of macromolecules into monomers (residues) carried out by digestive enzymes produced by salivary glands
