Exam 4 Part 5

Question 1

lobule

Answer 1

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

Question 2

portal triad

Answer 2

at periphery of lobule; contaisn artery, vein, bile duct

Question 3

artery in portal triad

Answer 3

arterial blood (high in O2)
from hepatic artery <- aorta

Question 4

vein in portal triad

Answer 4

venous blood (low in O2)
<- GI tract

Question 5

gall bladder

Answer 5

sac-like,stores and concentrates bile (about 10x)

Question 6

bile

Answer 6

greenish fluid produced by liver; fat digestion

Question 7

pancreas

Answer 7

“sweatbreads”

mixed gland

Question 8

pancreas exocrine function

Answer 8

produces digestive enzymes (pancreatic juice) in acinar cells; carrried to duodenum via pancreatic duct

Question 9

pancreas endocrine function

Answer 9

produces hormones (for blood sugar regulation) in islet cells via blood

Question 10

biliary apparatus

Answer 10

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

Question 11

common hepatic duct

Answer 11

Left and right hepatic ducts merge

Question 12

cystic duct

Answer 12

connects gallbladder to common hepatic duct

2 way transport

Question 13

common bile duct

Answer 13

common hepatic duct merges with cystic duct

connects to duodenum

Question 14

hepatopancreatic ampulla

Answer 14

common bile duct and pancreatic duct merge

Question 15

ampulla

Answer 15

swelling
