Name the six digestive processes?
- Ingestion
- Digestion
- Motility
- Secretion
- Absorption
- Elimination
- Regulation
Describe Ingestion?
Process of taking food into the mouth, starting its journey through the digestive tract
Describe Digestion?
A group of processes that break complex nutrients into simpler ones, thus facilitating their absorption: mechanical digestion physically breaks large chunks into smaller bits: chemical digestion breaks molecules apart
Describe Motility?
Movement by the muscular components of the digestive, including processes of mechanical digestion: examples include peristalsis and segmentation
Describe Secretion?
Release of digestive juice: some digestive organs also secrete endocrine hormones that regulate digestion or metabolism of nutrients
What do digestive juices contain?
Enzymes, acids, bases, mucus, bile or other products that facilitate digestion
