Amino acids
Small building blocks of proteins, released when proteins are digested
Adsorption
Passage of materials through the walls of the small intestines into the bloodstream
Amylase
Enzyme secreted by the 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 the RLQ).
Bile
Digestive juice made I. The liver and stored in the gallbladder. It break up large fat globules. Bike was originally calls gal, probably because it has a bitter taste
Bilirubin
Pigment released by the liver In bile
Bowel
Intestine
Canine teeth
Pointed, doglike teeth next to the incisors. Also called cuspids or eye teeth
Cecum
First part of the large intestines
Colon
Portion of the large intestine consisting of 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 from the digestive tract through the anus
Deglutition
Swallowing
Dentin
The primary material found in teeth. It is covered by the enamel In The crown and a protective later of cementum In the root
Digestion
Breakdown of complex foods to simpler foods
Duodenum
First part of the small intestine. Duo=2, den=10, the duodenum measures 12 inches long
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 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. Digestive enzymes break down complex foods to a simpler substance.
Esophagus
Tube connecting the throat to the stomach. Eso=inward; phag/o=swallowing
Fatty acids
Substances produced when days are digested
Feces
Solid waste. Stool
Gallbladder
Small sac under the liver, stores bile.
Glucose
Simple sugar
Glycogen
Starch, glucose is stored in the form of glycogen in liver cells
Hydrochloric acid
Substance produced by the stomach, necessary for digestion of food
Ileum
Third part of the small intestine, Greek meaning twisted. The ileum is often an area of obstruction
Incisor
One of the four front teeth I bathe dental arch
Insulin
Hormone produced by the endocrine cells of the pancreas. It transports sugar from the blood into cells and stimulates glycogen formation by the liver
Jejunum
Second part of the small intestines.
Lipase
Pancreatic enzyme necessary to digest fat
Liver
Large organ located In The RUQ of the abdomen. The liver secretes bile; stores sugar, iron, and vitamins; produces blood proteins; and destroys worn out red blood cells. The normal adult liver weighs about 2.5-3 pounds
Lower esophageal sphincter (LES)
Ring off sucked 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 and enzymes
Papillae
