30.3 The Digestive System
17
ingestion: is the process of putting food into your mouth.
digestion: it is broken down into two ways- by mechanical and chemical digestion, this process is called___________.
mechanical digestion: is the physical breakdown of large pieces of food into smaller pieces.
chemical digestion: enzymes break down food into the small molecules the body can use.
absorption: once food has been broken into small molecules, it can be absorbed by cells in the small intestine, this process is called___________.
elimination: Some materials, such as cellulose, travel through the large intestine and are eliminated from the body as feces, this process is called___________.
liver: produces bile, a fluid loaded with lipids and salts.
mouth: breaks down starches into dissacharides.
stomach: breaks down proteins into large peptides.
amylase: enzyme in saliva that breaks the chemical bonds in starches.
esophagus: tube connecting the mouth to the stomach.
peristalsis: contractions of smooth muscles that provide the force that moves food through the oesophagus toward the stomach.
pepsin: enzyme that breaks down proteins into smaller polypeptide fragments.
chyme: mixture of enzymes and partially-digested food
small intestine: digestive organ in which most chemical digestion and absorption of food takes place.
villi: fingerlike projection in the small intestine that aids in the absorption of nutrient molecules.
large intestine: organ in the digestive system that removes water from the undigested material that passes through it; also called colon.
