Mouth esophagus,
stomach,
small intestine - duodenum, jejunum ileum
Colon
rectum
anus
Accessory organs
Liver, GB, pancreas, salivary glands
Mouth digestion
MOUTH = salivary amylase = starches
salivary amylase breaks down
Begins where
starches
Mouth
Stomach digestion
gastric juice= gastrin, pepsinogens,
hydrochloric acid = proteins
Gastric juices
gastrin, pepsinogens,
hydrochloric acid
gastrin, pepsinogens,
hydrochloric acid break down
Proteins
PANCREAS digestion
= pancreatic amylase, lipase and
protease = starches, lipids & proteins
Pancreas via common bile duct
= pancreatic amylase, lipase and
protease = starches, lipids & proteins
pancreatic amylase, lipase and
protease break down
starches, lipids & proteins
LV/GB digestion
bile salts = emulsification of fats for
increased digestion
Bile salts
emulsification of fats for
increased digestion
Small intestine sections
duodenum, jejunum, illeum
Stomach connects to
duodenum
site of nutrient absorption
SI
Common Bile Duct delivers ________ to the chyme in the SI
pancreatic enzymes
and bile salts
Peyers patches live where?
SI
Absorption of water and essential vitamins
produced by the gut flora
LI
Converts digested food to fecal matter
LI
ileosecal valve is between
LI and SI
hepatic flexure
where the colon changes direction
Order of anatomy of LI
Ileosecal, secum, ascending colon, hepatic flexure, transverse, spenlic flexure, descending, sigmoid, rectum, anus
Mesentery
wraps around and holds LI and SI in place
