lanugo
fine, downy hair found on extremities, face, and trunk of pts with anorexia nervosa
absorption
passage of materials through the walls of the sm intestine into the bloodstream
amino acids
small building blocks of proteins, released when proteins are digested
amylase
enzyme secreted by pancreas 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; in RLQ
bile
digestive juice made in liver and stored in gallbladder; emulsifies large fat globules
bilirubin
pigment released by the liver in bile
bowel
intestine
canine teeth
pointed, dog-like teeth next to the incisors; aka cuspids or eyeteeth
cecum
first part of lg intestine
common bile duct
carries bile from liver and gallbladder to the duodenum; aka choledochus
defecation
elimination of feces from digestive tract through anus
deglutition
swallowing
dentin
primary material found in teeth
digestion
breakdown of complex foods to simpler forms
duodenum
first part of sm intestine (duo=2, den=10, so it measures 12 inches)
elimination
act of removal of materials from body; in digestive system, removal of indigestible materials as feces
emulsification
physical process of breaking up lg fat globules into smaller ones, thereby increasing the SA that enzymes can use to digest the fat
enamel
hard, outermost layer of tooth
enzyme
chemical that speeds up a rxn b/t substances
esophagus
tube connecting throat to stomach
fatty acids
substances produced when fats are digested
feces
solid wastes; stool
gallbladder
small sac under liver; stores bile
glucose
simple sugar
glycogen
starch; glucose is stored in the form of glycogen in liver cells
HCl
substance produced by stomach; necessary for digestion of food
ileum
3rd part of sm intestine
incisor
one of four front teeth in dental arch
insulin
hormone produced by the endocrine cells of the pancreas; transports sugar from the blood into cells and stimulates glycogen formation by liver
jejunum
2nd part of sm intestine
lipase
pancreatic enzyme necessary to digest fats
liver
large organ located in RUQ; secretes bile; stores sugar, iron, & vitamins; produces blood proteins; destroys worn-out RBCs
lower esophageal sphincter
ring of muscles bt the esophagus and stomach
mastication
chewing
molar teeth
6th, 7th, and 8th teeth from the middle of either side of dental arch
palate

salivary gland within the cheek, just anterior to the ear
pharynx
back of throat
portal vein
lg vein bringing blood to liver from intestines
protease
enzyme that digests protein
pulp
soft tissue within a tooth, containing nerves and blood vessels
pyloric sphincter
ring of muscle at the end of stomach, near duodenum
pylorus
distal region of the stomach, opening to the duodenum
rectum
last section of lg intestine, connecting the end of the colon and anus
rugae
ridges on hard palate and wall of stomach
saliva
digestive juice produced by salivary glands
salivary glands
parotid, sublingual, and submandibular glands
sigmoid colon
4th and last, S-shaped segment of the colon, just before the rectum; empties into the rectum
sphincter
circular ring of muscle that constricts a passage or closes a natural opening
