Terms (Ch 5) Flashcards
absorption
passage of materials through the walls of the small intestine to the bloodstream
amino acids
small building blocks of proteins; released when proteins are digested
amylase
enzyme that digests starch; released by the pancreas and salivary glands
anus
terminal end or opening of the digestive tract to the outside of the body
appendix
blind pouch hanging from the cecum (RLQ)
bile
digestive juice made in the liver and stored in the gallbladder; breaks up large fat globules
bilirubin
pigment released by the liver in bile
bowel
intestine
canine teeth
pointed, dog-like teeth; next to the incisors
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 duodenum; also called the choledochus
defecation
elimination of feces through the anus
deglutition
swallowing
digestion
breakdown of complex foods to simpler forms
duodenum
first part of the small intestine (12 in. long)
elimination
removal of materials from the body; in digestive system: removal of indigestible materials as feces
emulsification
breaking up large fat globules into smaller globules (increases surface area that enzyme can access to digest the fat)
enamel
hard, outermost layer of a tooth
enzyme
chemical that speeds up a reaction; in digestion: break down complex foods to simpler substances
esophagus
tube connecting the throat to the stomach
fatty acids
substances produced when fats are digested
feces
solid wastes
gallbladder
small sac under the liver; stores bile
glucose
simple sugar
glycogen
starch; glucose is stored as this in liver cells
hydrochloric acid
strong acid produced in stomach; aids digestion
ileum
third part of the small intestine
incisor
four front teeth
insulin
hormone produced by endocrine cells in pancreas; transports sugar to body cells
jejunum
second part of the small intestine
lipase
pancreatic enzyme necessary to digest fats
liver
in the RUQ; secretes bile; stores sugar, iron, and vitamins; destroys worn out RBCs; filters out toxins
lower esophageal sphincter
also called cardiac sphincter; ring of muscles between the esophagus and the stomach
mastication
chewing
molar teeth
three large, flat teeth at the back of the mouth
palate
roof of the mouth; hard palate= anterior to soft palate
pancreas
behind the stomach; produces insulin and enzymes
papillae
small projections on the tongue; taste buds are within them
parotid gland
salivary gland in the cheek and anterior to the ear
