16
Q

are caudate and quadrate lobe part of R or L lobe liver?

A

anatomically, they are subdivisions of right lobe BUT physiologically, they are part of L (same blood supply, nerve, bile)

17
Q
A
  1. caudate
  2. quadrate
18
Q
A

1.hepatic artery proper
2. hepatic portal vein
3. porta hepatis
4. IVC
5.coronary ligament
6.common bile duct

19
Q

where is caudate lobe

A

R lobe.
posterior, next to IVC

20
Q

porta hepatis

A

3 main structures:
1. common bile duct
2. hepatic porta vein
3. hepatic artery proper (branch of celiac)

21
Q

main fxn liver

A

produce bile, which emulsifies fat so that enzymes that digest fat have more SA to act on. co

22
Q

fxn gall bladder

A

concetration bile, then inject into duodenum

23
Q
A
  1. right hepatic duct
  2. cystic duct
  3. neck of gallbladder
  4. body of gallbladder
  5. fundus of gallbladder
  6. common bile duct
  7. left hpeatic duct
  8. common epatic duct
24
Q

hepatic ducts

A

R collects bile from R lobe, L from left lobe and caudate and quadrate

join together to form common hepatic duct (drains entire liver)

common hepatic duct receives cystic duct and then necomes common bile duct

25
Q

flow of bile

A

L and R hepatic duct pass bile to common hepatic duct, dilute bile goes through cystic duct, enters gall bladder, concentrated. When needed, passed again thru cystic duct, but goes DOWN common bile duct and injected into duodenum (SECOND PART)

26
Q
A
  1. common bile duct
  2. major duodenal papilla
  3. main pancreatic duct
  4. tail of pancreas
27
Q

explain location pancreas

A

head is partially surrounded by duodenum
body sits behind stomach
tail extens to hilum of spleen

retroperitoneal organ. fixed to posterior abdo wall by peritoneum

28
Q

fxn pancreas

A

endocrine and exocrine. produces hormones and digestive enzymes

29
Q

fxn pancreatic duct

A

drain exocrine features of pancreas (digestize enzymes). unites with common bile duct and drains into major duodenal papilla

30
Q

sympathetic/PSN supply to liver and gall bladder

A

greater splachnic and vagus nerve via celiac plexus

31
Q

blood supply liver/gall bladder

A

common hepatic branch of celiac artery

32
Q

sympathetic/PSN supply to pancreas

A

greater splachnic and vagus nerve via celiac and superior mesenteric plexuses

33
Q

blood supply pancreas

A

common hepatic and splenic branche of celiac artery as well as superior mesenteric artery

34
Q

which organs does celiac artery supply

A

stomach, spleen, pancreas, liver
