dysentery | painful, inflamed intestines |
hemorrhoids | swollen, twisted, vericose veins in the rectal region |
ileus | failure of peristalsis with resulting obstruction of the intestines |
intussusception | telescoping of the intestines |
irritable bowel syndrome (IBS) | group of gastrointestinal symptoms associated with stress and tension |
ulcerative colitis | chronic inflammation of the colon with presence of ulcers |
volvulus | twisting of the intestine on itself |
cholelithiasis | gallstones in the gallbladder |
cirrhosis | chronic degenerative disease of the liver |
pancreatitis | inflammation of the pancreas |
viral hepatitis | inflammation of the liver caused by a virus |
absorption | passage of materials through the walls of the small intestine into the bloodstream |
amino acids | building blocks of proteins, produced when proteins are digested |
amylase | enzyme secreted by the pancreas to digest starch |
anus | opening of the digestive tract to the outside of the body |
appendix | blind pouch hanging from the cecum (in the right lower quadrant |
bile | digestive juice made in the liver and stored in the gallbladder. it breaks up (emulsifies) large fat globules |
bilirubin | pigment released by the liver in bile |
bowel | intestine |
canine teeth | pointed, "dog tooth"-like teeth, next to (distal to) the incisors. also called cuspids or eyeteeth |
cecum | first part of the large intestine |
colon | large intestine, consisting of the cecum; the ascending, transverse, and decending segments; and the rectum |
common bile duct | carries bile from the liver and gallbladder to the duodenum. also called the choledochus |
defecation | elimination of feces from the digestive tract through the rectum |
deglutition | swallowing |
dentin | major tissue composing teeth, covered by the enamel in the crown and a protective layer of cementum in the root |
digestion | breakdown of complex foods into simpler forms |
duodenum | first part of the small intestine |
elimination | act of removal of materials from the body; in the digestive system, the removal of indigestible materials |
emulsification | physical process of breaking up large fat globules into smaller globules, thereby increasing the surface area that enzymes can use to digest the fat |
enamel | hard, outermost layer of a tooth |
enzyme | a chemical that speeds up a reaction between substances |
esophagus | tube connecting the throat to the stomach |
fatty acids | substances produced when fats are digested |
feces | solid wastes; stools |
gallbladder | small sac under the liver; stores bile |
glucose | simple sugar |
glycogen | starch; glucose is stored in this form in liver cells |
hydrochloric acid | substance produced by the stomach; necessary for digestion of food |
ileum | third part of the small intestine; from the Greek eilos, meaning twisted. when the abdomen was viewed at autopsy, the intestine appeared twisted, and the ilium often was an area of obstruction |
incisor | one of four front teeth in the dental arch |
insulin | hormone produced by the endocrine cells of the pancreas. it transports sugar from the blood into the cells and stimulates glycogen formation by the liver |
jejunum | second part of the small intestine |
lipase | pancreatic enzyme necessary to digest fats |
liver | a large organ located in the RUQ of the abdomen. secretes bile; stores sugar, iron, and vitamins; produces blood proteins; and destroys worn out red blood cells |
lower esophageal sphincter (LES) | ring of muscles between the esophagus and the stomach. also called cardiac sphincter |
mastication | chewing |
molar teeth | the sixth, seventh, and eighth teeth from the middle on either side of the dental arch |
palate | roof of the mouth |
pancreas | organ under the stomach; produces insulin (for transport of sugar into cells) and enzymes (for food digestion) |
papollea | small elevations om=n the tongue |
parotid gland | salivary gland within the cheek, just anterior to the ear |
peristalsis | rhythmic contractions of the tubes of the gastrointestinal (GI) tract and other tubular structures. moves the contents through the GI tract at different rates: stomach, 0.5 to 2 hours; small intestine, 2 to 6 hours; and colon, 6 to 72 hours |
pharynx | throat, the common passageway for food from the mouth and for 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, containing nerves and blood vessels |
pyloric sphincter | ring of muscle at the end of the stomach, neat the duodenum. it is normally closed, but opens when a wave of peristalsis passes over it |
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 glands | paratid, sublingual, and submandibular glands |
sigmoid colon | fourth and last S-shaped segment of the colon, just before the rectum; empties into the rectum |
sphincter | circulating ring of muscle that constricts a passage or closes a natural opening |
stomach | muscular organ that receives food from the esophagus |
