Processes
Mechanically or Chemically breaking down food
Digestion
Innermost layer of GI tract
mucosa
Site for ingestion
Mouth
Cell that produces intrinsic factor and hydrochloric acid
Chief cells
Pancreatic enzyme responsible for breaking polysaccharides into oligosaccharides
Pancreatic amylase
Taking food in through the mouth
Ingestion
Layer of GI tract responsible for peristalsis
Muscularis
Dual passageway for air, food, and liquid
Pharyx
"Mixing bowl" of the small intestine
Duodenum
intestinal enzyme responsible for breaking dipeptides into amino acids
Dipeptidase
Movement of materials across the GI tract wall
Absorption
Layer of GI tract that contains buffer-secreting exocrine glands
Submucosa
Modified portion of GI tract that contains gastric pits
Stomach
Surface in the mouth that can be used for mashing food
Hard palate
Pancreatic enzyme responsible for breaking oligopeptides into small peptides
Trypsin
Voluntary or involuntary movement of food through the GI tract
Propulsion
Plexus that innervates the mucosa
Plexus of Meissner
Intestine directly associated with the stomach
Small intestine
Large intestine
Intestinal enzyme responsible for breaking oligosaccharides into monosaccharides
Maltase
OR
Sucrase
OR
Lactase
Expulsion of undigested food and waste
Defecation
Layer that forms the messentary
Serosa
Intestine that houses microbiota such as fungi, bacteria
Large intestine
Accessory organ that produces bile
Liver
Pancreatic enzyme responsible for breaking triglycerides into free fatty acids
Pancreatic lipase
