Exam 4 Part 5 Flashcards
lobule
functional unit of liver
at periphery: portal triad
at center: central vein
drains blood from 2 of 3 triad vessels
blood mixes in sinusoid on way to central vein
from central vein: blood -> hepatic vein -> inferior vena cava
portal triad
at periphery of lobule; contaisn artery, vein, bile duct
artery in portal triad
arterial blood (high in O2) from hepatic artery <- aorta
vein in portal triad
venous blood (low in O2) <- GI tract
gall bladder
sac-like,stores and concentrates bile (about 10x)
bile
greenish fluid produced by liver; fat digestion
pancreas
“sweatbreads”
mixed gland
pancreas exocrine function
produces digestive enzymes (pancreatic juice) in acinar cells; carrried to duodenum via pancreatic duct
pancreas endocrine function
produces hormones (for blood sugar regulation) in islet cells via blood
biliary apparatus
network of ducts: not blood vessels
L & R hepatic ducts (from liver) merge -> common hepatic duct
cystic duct
common hepatic duct and cystic duct -> common bile duct
bile duct and pancreatic duct -> hepatopancreatic ampulla
common hepatic duct
Left and right hepatic ducts merge
cystic duct
connects gallbladder to common hepatic duct
2 way transport
common bile duct
common hepatic duct merges with cystic duct
connects to duodenum
hepatopancreatic ampulla
common bile duct and pancreatic duct merge
ampulla
swelling
excretion
involves repiratory, digestive, integumentary, and urinary systems
urinary system components
kidneys, ureters, urinary bladder, urethra
kidney macroscopic anatomy
hilum adipose capsule medulla subdiveds into pyramids renal papilla renal pelvis ureter calyx
hilum
where a lot of vessels and tubes enter an organ
renal papilla
at apex of each pyramid
calyx
branches of renal pelvis
pl clayces
kidney microscopic anatomy
nephron
