amino acids
small building blocks of proteins, released when proteins are digested
amylase
enzyme (-ase) secreted by the pancreas and salivary glands to digest starch
bile
digestive juice made in the liver and stored in the gallbladder. Breaks up large fat globules
cecum
first part of the large intestine
common bile duct
carries bile from the liver and gallbladder to the duodenum. Also called choledochus
deglutition
swallowing
emulsification
breaking up large fat globules into smaller globules, increasing surface area that enzymes can use to digest the fat
enzyme
chemical that speeds up a reaction between substances
esophagus
tube connecting the throat to the stomach
gallbladder
small sac under the liver; stores bile
glucose
simple sugar
glycose
starch
hydrochloric acid
substance produced in the stomach; aids digestions
ileum

lipase
pancreatic enzyme necessary to digest fats
lower esophageal sphincter (LES)
ring of muscles between the esophagus and the stomach. Also called cardiac sphincter
mastication
chewing
palate
roof of mouth
pancreas
organ behind the stomach; produces insulin and enzymes
papillae
small projections on the tongue. Taste buds are within the papillae
parotid gland
salivary gland within the cheek, just anterior to the ear
peristalsis
rhythmic contractions of the tubular organs
pharynx
throat, the common passageway for food from the mouth and air from the nose
portal vein
large vein bringing blood to the liver from the intestines
protease
enzyme that digests protein
pulp
soft tissue within a tooth, contains nerves and blood vessels
pyloric sphincter
ring of muscle at the end of the stomach, near the duodenum
pylorus
distal region of the stomach, opening to the duodenum
rugae
ridges on the hard palate and the wall of the stomach
saliva
digestive juice produces by salivary glands
sigmoid colon
lower, S-shaped segment of the colon, just before the rectum; empties into rectum
triglycerides
fat molecules composed of three parts fatty acids and one part glycerol. Subgroup of lipids
uvula
soft tissue hanging from the middle of the soft palate
villi
microscopic projections in the wall of the small intestine that absorb nutrients into the bloodstream
