Chapter 5 Med Terms Flashcards
Passage of materials through the walls of the small intestine into the bloodstream
Absorption
Small building blocks of proteins, released when proteins are digested.
Amino acids
Enzyme (-ase) secreted by the pancreas and salivary glands to digest starch (amyl/o).
Amylase
Terminal end or opening of the digestive tract to the outside of the body
Anus
Blind pouch hanging from the cecum (in the right lower quadrant [RLQ]). It literally means hanging (pend/o) onto (ap-, which is a form of ad-).
Appendix
Digestive juice made in the liver and stored in the gallbladder. It breaks up (emulsifies) large fat globules.
Bile
Pigment released by the liver in bile
Bilirubin
Intestine
Bowel
Pointed, dog-like teeth (canine means pertaining to dog) next to the incisors. Also called cuspids or eyeteeth
Canine
First part of large intestine
Cecum
Portion of the large intestine consisting of the ascending, transverse, descending, and sigmoid segments
Colon
Carries bile from the liver and gallbladder to the duodenum. Also called the choledochal
Common bile duct
Elimination of feces from the digestive tract through the anus
Defecation
Swallowing
Deglutition
Primary material found in teeth. It is covered by the enamel in the crown and a protective layer of cementum in the root
Dentin
Breakdown of complex foods to simpler forms
Digestion
First part of the small intestine. Duo = 2, den = 10; the duodenum measures 12 inches long
Duodenum
Removal of materials from the body; in the digestive system, the removal of indigestible materials as feces
Elimination
Breaking up large fat globules into smaller globules. This increases the surface area that enzymes can use to digest the fat
Emulsification
Hard, outermost layer of a tooth
Enamel
Chemical that speeds up a reaction between substances
Enzyme
Tube connecting the throat to the stomach
Esophagus
Substances produced when fats are digested
Fatty acids
Solid wastes; stool. Term fecal means pertaining to feces
Feces
Small sac under the liver; stores bile
Gallbladder
Simple sugar
Glucose
Starch; Glucose is stored in the form of glycogen in liver cells
Glycogen
Substance (strong acid) produced in the stomach; aids digestion
Hydrochloric acid
Third part of the small intestine from the Greek eilos, meaning twisted
Ileum
Any of 1-4 front teeth in the dental arch
Incisor
Hormone produced by the endocrine cells of the pancreas. It helps transport sugar into body cells
Insulin
Second part of the small intestine
Jejunum
Pancreatic enzyme necessary to digest fats
Lipase
Large organ located in the RUQ of the abdomen. The liver secretes bile; stores sugar, iron, and vitamins; produces blood proteins; destroys worn-out red blood cells; and filters out toxins
Liver
Ring of muscles between the esophagus and the stomach. Also called cardiac sphincter
Lower esophageal sphincter
Chewing
Mastication
Three large, flat teeth at the back of the mouth, on either side of the dental arch
Molar teeth
Roof of the mouth
Palate
Lies anterior to the soft palate and is supported by the upper jawbone (maxilla
Hard palate
Posterior fleshy part between the mouth and the throat
Soft palate
Organ behind the stomach; produces insulin (for transport of sugar into cells) and enzymes (for digestion of foods)
Pancreas
Small projections on the tongue. Tastebuds are located here
Papillae
Salivary gland within the cheek, just anterior to the ear
Parotid gland
Rhythmic contractions of the tubular organs
Peristalsis
Throat, the common passageway for food from the mouth and for air from the nose
Pharynx
Large vein bringing blood to the liver from the intestines
Portal vein
Enzyme that digests protein
Protease
Soft tissue within a tooth
Pulp
Ring of muscle at the end of the stomach, near the duodenum
Pyloric sphincter
Distal region of the stomach, opening to the duodenum
Pylorus
Last section of the large intestine, connecting the end of the colon and the anus
Rectum
Ridges on the hard palate and the wall of the stomach
Rugae
Digestive juice produced by salivary glands
Saliva
Parotid, subinguinal, and submandibular glands
Salivary gland
Lower, S-shaped segment of the colon, just before the rectum; empties into the rectum
Sphincter
Muscular organ that receives food from the esophagus
Stomach
Fat molecules composed of three parts fa y acids and one part glycerol
Triglycerides
Soft tissue hanging from the middle of the soft palate
Uvula
Microscopic projections in the wall of the small intestine that absorb nutrients into the bloodstream
Villi
An/o
Anus
Append/o
Appendix
Bucc/o
Cheek
Mucous membrane lining cavities or canals that open to the outside of the body
Buccal mucosa
Cec/o
Cecum
Celi/o
Bell, abdomen
Damage to the lining of the small intestine, occurring as a reaction to eating gluten
Celiac
Cheil/o
Lip
Cholecyst/o
Gallbladder
Choledoch/o
