main functions of the GI system
- ingestion
- digestion
- absorption
- elimination
Parts of the oral cavity
cheeks, lips, hard palate, soft palate, rugae, uvula, tongue, papillae, tonsils, gums, teeth, pharynx
parts of tooth
crown, root, enamel, dentin, pulp, gingiva, cementum, root canal, periodontal membrane
parts of stomach
lower esophageal sphincter (LES), Fundus, greater curvature, lesser curvature, rugae, body, antrum, pylorus, pyloric sphincter
Parts of the digestive tract
Esophagus, stomach, duodenum, liver, gallbladder, pancreas, jejunum, ileum, cecum, appendix, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, anus
parts of Large intestine
Cecum, appendix, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, anus
Parts of liver, gallbladder, pancreas
hepatic duct
cystic duct
common bile duct
pancreatic duct
duodenum
What does pancreas produce
insulin and enzymes
amylase
enzyme secreted by pancreas and salivary glands to digest starch
bile
digestive juice made in liver and stored in gallbladder; breaks up large fat globules; composed of bile pigments, cholesterol, and bile salts
bilirubin
pigment released by the liver in bile
deglutition
swallowing
lipase
pancreatic enzyme needed to digest fats
mastication
chewing
parotid gland
salivary glad w/in cheek, anterior to ear
peristalsis
rhythmic contractions of the tubular organs
portal vein
large vein bringing blood to the liver from the intestine
protease
enzyme that digests protein
pylorus
