Answers
digestive tract - CORRECT ANSWER - also called alimentary tract or canal
GI Tract - CORRECT ANSWER - technically refers to stomach and intestines
where do accessory organs secrete fluids into? - CORRECT ANSWER - tract
oral cavity - CORRECT ANSWER - mouth, includes tongue and teeth
what are salivary glands accessory organs to? - CORRECT ANSWER - the mouth
pharynx - CORRECT ANSWER - throat
what are tonsils accessory organs to? - CORRECT ANSWER - the pharynx
small intestines - CORRECT ANSWER - duodenum, jejunum, ileum
what are accessory organs to the small intestines? - CORRECT ANSWER - liver,
gallbladder, and pancreas
what does the large intestine include? - CORRECT ANSWER - cecum, colon, rectum, anal
canal
regions of the digestive system - CORRECT ANSWER - mouth, pharynx, esophagus,
stomach, small intestines, large intestines
,functions of the digestive system - CORRECT ANSWER - ingestion, mastication,
propulsion, mixing, secretion, digestion, absorption, elimination
ingestion - CORRECT ANSWER - intake of solid or liquid food into the stomach through
the oral cavity
mastication - CORRECT ANSWER - breaks food into smaller particles for better
penetration of digestive enzymes
propulsion - CORRECT ANSWER - movement of food through the digestive tract
deglutition - CORRECT ANSWER - process of swallowing (oral cavity to esophagus)
peristalsis - CORRECT ANSWER - rhythmic muscluar contractions (esophagus to large
intestine)
examples of propulsion - CORRECT ANSWER - deglutition, peristalsis, mass movements
mixing - CORRECT ANSWER - segmental contractions that move material back and
forth; break food into smaller pieces and mix particles with digestive secretions
secretion - CORRECT ANSWER - lubricate, liquefy, buffer, and digest food
mucus secretion - CORRECT ANSWER - lubricates food and coats lining to protect from
mechanical abrasion, acid, and digestive enzymes
water secretion - CORRECT ANSWER - liquefies food to make it easier to digest and
absorb
, bile secretion - CORRECT ANSWER - emulsifies fat
enzymes secretion - CORRECT ANSWER - break down food molecules for better
absorption by intestinal wall
digestion - CORRECT ANSWER - breakdown of large organic molecules into component
parts
mechanical digestion - CORRECT ANSWER - mastication, mixing
chemical digestion - CORRECT ANSWER - enzymes
absorption - CORRECT ANSWER - movement from digestive tract into blood or lymph
elimination - CORRECT ANSWER - waste products of digestive (feces) are removed
from body by defecation
4 tunics of the digestive tract - CORRECT ANSWER - mucosa, submucosa, muscularis,
serosa/adventitia
mucosa - CORRECT ANSWER - innermost layer composes of mucous epithelium, lamina
propria, and muscularis mucosae
mucous epithelium - CORRECT ANSWER - stratified squamous in mouth, pharynx,
esophagus, and anal canal and simple columnar epithelium in the rest of the tract
lamina propria - CORRECT ANSWER - loose connective tissue and epithelium extends
into the lamina propria to form glands and crypts
