Term
ABSORPTION

COLON
Definition
LARGE INTESTINE, CONSISTING OF THE CECUM, THE ASCENDING, TRNASVERSE, AND DESCENDING SEGMENTS, AND THE RECTUM.
Term
COMMON BILE DUCT
Definition
CARRIES BILE FROM THE LIVER AND GALLBLADDER TO THE DUODENUM.  ALSO CALLED THE CHOLEDOCHUS.
Term
DEFECATION
Definition
ELIMINATION OF FECES FROM THE DIGESTIVE TRACT THROUGH THE ANUS.
Term
DEGLUTITION
Definition
SWALLOWING
Term
DENTIN
Definition
THE PRIMARY MATERIAL FOUND IN TEETH.  IT IS COVERED BY THE ENAMEL IN THE CROWN AND A PROTECTIVE LAYER OF CEMENTUM IN THE ROOT.
Term
DIGESTION
Definition
BREAKDOWN OF COMPLEX FOODS TO SIMPLER FORMS.
Term
DUODENUM
Definition
FIRST PART OF THE SMALL INTESTINE.  IT MEASURES 12 INCHES LONG.
Term
ELIMINATION
Definition
ACT OF REMOVAL OF MATERIALS FROM THE BODY; IN THE DIGESTIVE SYSTEM, THE REMOVAL OF INDIGESTIBLE MATERIAL AS FECES.
Term
EMULSIFICATION
Definition
PHYSICAL PROCESS OF BREAKING UP LARGE FAT GLOBULES INTO SMALLER GLOBULES, THEREBY INCREASING THE SURFACE AREA THAT ENZYMES CAN USE TO DIGEST THE FAT.
Term
ENAMEL
Definition
HARD, OUTERMOST LAYER OF A TOOTH.
Term
ENZYME
Definition
A CHEMICAL THAT SPEEDS UP A REACTION BETWEEN SUBSTANCES.  THEY BREAK DOWN COMPLEX FOODS TO SIMPLER SUBSTANCES.  THEY ARE GIVEN NAMES THAT END IN -ASE.
Term
ESOPHAGUS
Definition
TUBE CONNECTING THE THROAT TO THE STOMACH.  ESO- MEANS INWARD; PHAG/0 MEANS SWALLOWING.
Term
FATTY ACIDS
Definition
SUBSTANCES PRODUCED WHEN FATS ARE DIGESTED.
Term
FECES
Definition
SOLID WASTE; STOOL
Term
GALLBLADDER
Definition
SMALL SAC UNDER THE LIVER; STORES BILE.
Term
GLUCOSE
Definition
SIMPLE SUGAR
Term
GLYCOGEN
Definition
STARCH; GLUCOSE IS STORED IN THE FORM OF THIS IN LIVER CELLS.
Term
HYDROCHLORIC ACID
Definition
SUBSTANCE PRODUCED BY THE STOMACH; NECESSARY FOR DIGESTION OF FOOD.
Term
ILEUM
Definition
THIRD PART OF THE SMALL INTESTINE.  FROM THE GREEK WORD EILOS, MEANING TWISTED. 
Term
INCISOR
Definition
ON OF FOUR FRONT TEETH IN THE DENTAL ARCH
Term
INSULIN
Definition
HORMONE PRODUCED BY THE ENDOCRINE CELLS OF THE PANCREAS.  IT TRANSPORTS SUGAR FROM THE BODY INTO CELLS AND STIMULATES GLYCOGEN FORMATION BY THE LIVER.
Term
JEJUNUM
Definition
SECOND PART OF THE SMALL INTESTINE.  THIS PART OF THE INTESTINE WAS ALWAYS EMPTY WHEN A BODY WAS EXAMINED AFTER DEATH.
Term
LIPASE
Definition
PACREATIC ENZYME NECESSARY TO DIGEST FATS.
Term
LIVER
Definition
A LARGE ORGAN LOCATED IN THE RUQ OF THE ABDOMEN.  IT SECRETES BILE; STORES SUGAR, IRON, AND VITAMINS; PRODUCES BLOOD PROTEINS; AND DESTROYS WORN-OUT RED BLOOD CELLS.  NORMAL ONE WEIGHS ABOUT 2 1/2 TO 3 POUNDS.
Term

Term
PALATE
Definition
ROOF OF THE MOUTH. 
Term

Definition
ORHAN UNDER THE STOMACH; PRODUCES INSULIN (FOR TRANSPORT OF SUGAR INTO CELLS) AND ENZYMES (FOR DIGESTION OF FOOD).
Term

Definition
SMALL ELEVATIONS ON THE TONGUE.  IT IS A NIPPLE-LIKE ELEVATION.
Term
PAROTID GLAND
Definition
SALIVAR GLAND WITHIN THE CHEEK, JUST ANTERIROR TO THE EAR.
Term
PERISTALSIS
Definition
RHYTHMIC CONTRACTIONS OF THE TUBULAR ORGANS.  IN THE GASTROINTESTINAL TRACT, THIS MOVES THE CONTENTS THROUGH AT DIFFERENT RATES: STOMACH, 0.5 TO 2 HOURS; SMALL INTESTINE, 2 TO 6 HOURS; AND COLON, 6 TO 72 HOURS.
Term
