HBS Digestive System
protein digestion - ✔️✔️starts in the stomach with pepsin, which converts polymers of
amino acids into short chains of amino acids called peptides, continues with proteolytic
enzymes coming from the pancreas, which does the same action as pepsin, and is
finished with peptidase, which comes from the small intestine, and it converts peptides
into individual amino acids
carbohydrate digestion - ✔️✔️starts in the mouth with amylase converting
polysaccharides to disaccharides, continues with pancreatic amylase, finishes with
sucrase/maltase/lactase from the small intestine converting disaccharides to
monosaccharides (glucose/fructose/galactose)
salivary glands - ✔️✔️make saliva
tongue - ✔️✔️it helps to mix food with saliva during chewing, moves food toward the
pharynx during swallowing, and moves food under teeth for chewing; it also has taste
cells on it for tasting that are contained within taste buds
bolus - ✔️✔️mass of chewed food mixed with saliva
hard palate - ✔️✔️contains the maxilla bone, forms the upper/anterior part of oral
cavity
soft palate - ✔️✔️extends posterior of the hard palate and is muscular, ends in the
uvula, helps in swallowing
mechanical digestion - ✔️✔️the physical breakdown of food into smaller pieces by the
mouth/teeth, increases surface area for chemical digestion and prevents choking
epiglottis - ✔️✔️a flap-like structure located on top of the larynx, during swallowing, the
trachea raises and the epiglottis covers the opening to the trachea hopefully ensuring
that nothing goes down the trachea and therefore into the lungs
peristalsis - ✔️✔️rhythmic waves of muscular contraction in the walls of the alimentary
canal; it helps to move through the canal
stomach - ✔️✔️receives food from the esophagus and mixes food with gastric juice to
produce chyme, begins the chemical digestion of proteins, carries on limited absorption
(some water, certain salts, certain lipid-soluble drugs, and some alcohol), and moves
food into the small intestine
