PN 110 digestion


lymph vessels that absorb fat in the small intestine lacteal
the three sections of the small intestine duodenum jejunum ileum
what happens in the mouth that aids digestion mechanical digestion-chewing chemical digestion-enzymes
the tube that carries a bolus to the stomach esophagus
the name for chewed food and saliva as it is chewed/swallowed bolus
watery mixture of food and digestive juices chyme
top, rounded part of the stomach fundus
sphincter at the top of the stomach lower esophageal sphincter
sphincter at the bottom of the stomach pyloric sphincter
the opening from the stomach to the small intestine pylorus
folds of the stomach rugae
having to do with stomach gastric
having to do with liver hepatic
collects/stores bile gall bladder
helps emulsify fats bile
organs which produce and secrete digestive enzymes into the small intestine pancreas liver
this organ is like a cement mixer and has a very low pH stomach
nutrients are absorbed here small intestine
functions to reabsorb water large intestine (colon)
three sections of the large intestine (colon) ascending transverse descending
muscular portion of the large intestine near the end rectum
finger-like folds in the small intestine used to absorb nutrients villi
wavelike contractions that help move things along the digestive tract peristalsis
things that decrease infection from harmful germs that we injest saliva hydrochloric acid in stomach
this helps us absorb vitamin B12 intrinsic factor
this is secreted by the stomach, and causes an increase in stomach acid gastrin
these cells secret protective mucus goblet cells
widened area where the common bile duct and the pancreatic duct meet Ampulla of Vater
the duct from the gall bladder cystic duct
formed when the hepatic duct and cystic duct join common bile duct
muscular sphincter that controls the flow of digestive juices into the small intestine (from the liver and pancreas) sphincter of Oddi
covers teeth, and is one of the hardest substances in the body enamel
number of lobes in the liver four
right and left lobes are separated by the _________________ ligament falciform
valve that joins the small intestine to the large intestine ileocecal valve
as we age, peristalsis tends to slow down
enzyme in saliva that breaks down starch amylase
tubular organ attached to the lower end of the cecum: serves as a source for immune cells appendix
enzyme that digests fat lipase
saliva glands parotid submandibular sublingual
teeth that we lose ("baby teeth") deciduous teeth
cells in the stomach which secrete digestive enzymes chief cells
which side of the body do we find our liver right side
stomach acid neutralized in this part of the small intestine duodenum
waste products in the large intestine feces
section of small intestine where most digestion occurs duodenum
section of small intestine where most absorption of nutrients occurs jejunum
section of small intestine where vitamin B12 absorbed ileum fun fact: intrinsic factor (from stomach) must be present for B12 to be absorbed by the ileum
this contracts to protect the nasal cavity during a swallow soft palate
three sets of salivary glands parotid, sublingual, submandibular
layer of muscles in the GI tract these help with peristalsis muscularis
innermost layer of the GI tract mucosa
layer of GI tract which contains nerves, blood vessels, and lymph vessels submucosa
protease that is secreted by the stomach pepsin
This acid assists with food breakdown. It also kills some germs that enter the stomach. hydrochloric
this monosaccharide is used extensively by the body (the brain relies on this for its main source of energy) glucose
type of enzyme that breaks down protein protease
type of enzyme that breaks down fats lipase
type of enzyme that breaks down carbohydrates amylase
these two organs provide chemicals or enzymes that help with digestion in the small intestine pancreas (pancreatic enzymes) liver (produces bile)
outermost layer of the GI tract serosa (visceral peritoneum)
lining of the abdominal cavity peritoneum
difficult swallowing dysphagia
a fold of tissue that anchor organs to the body wall mesentery
section of visceral peritoneum that hangs down from the stomach. Known as the "fatty apron." greater omentum
part of GI tract with low pH (acid) stomach
part of GI tract with alkaline pH small intestine
inflammation of the pancreas pancreatitis
related to the liver hepatic
related to the stomach gastric
name of the protease in stomach pepsin
