Ch. 25 Day 2 Flashcards
first region of small intestine
duodenum
duodenum recieves
chyme, enxymes from pancrease
bile from gallbladder
jejunum is bulk of
chemical digestion and nutrient absorptions
second region of small intestine
jejunum
third region of small intestine is the
ileum
ilium controls
material flow into large intestine
small intestine folds
circular folds plicae
finger like projections extending into lumen
intestinal villi
small intestine cells
goblet cells secreting mucus
intestinal glands have
enteroendocrine cells and stem cells
specilized lympahetics
lacteals
lipids go into
lacteals
aggregated lymphoid nodules are
peyers patches
peyers patches protect against
bacteria migrating from large intestine
large intestine functions
aborb water
electrolytes
vitamins
compaction and storage of feces
large insteine compared to small
less length bigger diameter
attached to cecum is
appendix
anal sphinter amount
2 of them
internal anal sphinter is
relax when you need to poop
external anal sphincter is
voluntary
large intestine thin walls with no
villi
large intestine cells for mucus secretion
goblet cells
large intestine amount of bacteria
500 diff types
intestinal bacteria release
irritating acids and mixture of gases
intestinal bacteria synthesize
b complex vitamins
vitamin K
liver functions
iron, vitamin, glycogen storage
detoxifaction
interconversion of nutreint types
liver removes
old blood cells
liver synethesizes
plasma proteins
liver produces
bile
liver divided into
4 lobes/segments
cells for the liver are
hepatocytes
hepatocytes are organized into
liver lobnules
plates of hepatocytes
sinusoids
sinusoids radiate around
central vein
liver blood flow order
interlobular artery
interlobular vein
sinusoids
central vein
hepatic veins
inferior vena cava
stellate macrophages (kupffer cells) in sinusoids
phagocytize pathogens, debris, damaged blkood cells, ingested heavy metals
bile helps us ingest
fats
bile is sytnthesized by
hepatocytes
bile is mostly
water
bile contains other than water
bilirubin, electrolytes
bile salts
bile salts reabsorbed into
ileum
bile flow
bile canaliculi
interlobular bile ducts
common hepatic duct
common bile duct
bile is mostly stored and concentrated by the
gallbladder
pancjreatic acini collects
pancreatic juice
pancreated juice collected from
acinar cells
pancreatic duct carries pancreatic juice to the
duodenal papilla
