absorption
passage of material through the walls of the small intestine into the bloodstream
amino acids
small building blocks of proteins released when proteins are digested
amylase
enzyme secreted by the pancreas and salivary glands to digest starch
anus
terminal end or opening of the digestive tract to the outside of the body
appendix
blind pouch hanging from the cecum
bile

pigment released by the live in bile
bowel
intestine
canine teeth

cecum
first part of the large intestine
colon
portion of the large intestine consisting of the ascending, transverse, descending, and sigmoid segments
common bile duct
carries bile from the liver and gallbladder to the duodnum
defecation
elimination of feces from the digestive tract through the anus
deglutition
swallowing
dentin
primary material found in teeth
digestion
breakdown of complex foods to simpler forms
duodenum
first part of the small intestine
elimination
act of removal of materials from the body
emulsification
physical process of breaking up large fat globules into smaller globules thereby increasing the surface area the enzymes can use to digest the fat
enamel
hard, outermost layer of a tooth
enzyme
chemical the speeds up a reaction between substances
esophagus
tube connecting the throat to the tomach
fatty acids
substances produced when fats are digested
feces
solid wastes

any one of four front teeth in the dental arch
insulin
hormone produced by the endocrine cells of the pancreas
jejunum
second part of the small intestine
lipase
pancreatic enzyme necessary to digest fats

large organ located in the RUQ of the abdomen
lower esophageal sphincter (LES)
ring of muscles between the esophagus and the stomach
mastication
chewing
molar teeth
sixth, seventh, and eight teeth from the middle on either side of the dental arch
palate
roof of the month
pancreas
organ behind the stomach, produces insulin
papillae
small projection of the tongue

salivary gland within the cheek
peristalsis
rhythmic contractions of the tubular organs

ring of muscle at the end of the stomach
pylorus
distal region of the stomach, opening to the duodenum
rectum
last section of the large intestine, connecting the end of the colon and the anus
rugae
ridges on the hard palate and the wall of the stomach
saliva
digestive juice produced by salivary glands
salivary gland
parotid, sublingual, and submandibular glands
sigmoid colon
fourth and last S- shaped segment of the colon, just before the rectum
sphincter
circular ring of muscle that constricts a passage or closes a natural opening
stomach
muscular organ that receives food from the esophagus
triglycerides
fat molecules composed of three parts fatty acids and one part glycerol
uvula
soft tissue hanging from the middle of the soft palate
