| Term | Definition |
|---|---|
| Ingestion | Process of taking food into the mouth, starting it on its journey through the digestive tract |
| Digestion | A group of processes that break complex nutrients into simpler ones, thus facilitating their absorption; mechanical digestion physically breaks large chunks into small bits; chemical digestion breaks molecules apar |
| Motility | Movement by the muscular components of the digestive tube, including processes of mechanical digestion; examples include peristalsis and segmentation |
| Secretions | Release of digestive juices (containing enzymes, acids, bases, mucus, bile, or other products that facilitate digestion); some digestive organs also secrete endocrine hormones that regulate digestion or metabolism of nutrients |
| Aborpstion | Movement of digested nutrients through the gastrointestinal (GI) mucosa and into the internal environment |
| Elimination | Excretion of the residues of the digestive process (feces) from the rectum, through the anus; defecation |
| Regulation | Coordination of digestive activity (motility, secretion, etc.) |
| Mastication | Mechanical digestion begins in the mouth when the particle size of ingested food material is reduced by chewing movements, |
| Deglutition | The process of swallowing, |
| Mechanical Digestion | consists of all movement (motility) of the digestive tract |
