Liver and gallbladder Flashcards
How many surfaces does the liver have?
5: Ant, post, sup, inf, right
Divided into right and left lobes by
Ant and sup: falciform
Inf: Ligamentum teres
Post: ligamentum venosum
Right lobe
Larger than left, caudate and quadrate lobes
Caudate
- post surface
- right: IVC
- left: fissure for ligamentum venosum
- inf: porta hepatis
- conn to right lobe by caudate process
Quadrate
- inferior surface
- rectangular
- ant: inferior border
- right: fossa for gall bladder
- left: fissure for ligamentum teres
Porta hepatis
- portal vein and hepatic artery
- hepatic plexus of nerves enters
- hepatic ducts leave
- VAD: (post to ant)- portal vein, hepatic artery, bile ducts
- lesser omentum attaches to lips of porta hepatis
Left lobe
- smaller than right
- rounded elevation near fissure for ligamentum venosum: omental tuberosity
Areas not covered by peritoneum
- bare area on post surf of right lobe
- groove for IVC
- fossa for gall bladder
- porta hepatis
Falciform lig
Att anterosup surface of liver to anterior abdominal wall and to under surface of diaphragm
Left triangular
Conn sup surface of left lobe of liver to diaphragm
Right triangular
Conn lateral part of post surface of right lobe to diaphragm
Coronary lig
Has sup and inf layers which encloses bare area of liver
What encloses lesser omentum?
Coronary lig
Fundus
Projects beyond inf border of liver
-surrounded by peritoneum, relation ant to ant abdom wall and post to transverse colon
Body
- sup surface has no peritoneum as it is attached to liver
- inf surface covered with peritoneum, related to transverse colon and duodenum
Neck
- situated near right end of porta hepatis
- joins with cystic duct
- att sup to liver and rel inf to duodenum
- Hartmann’s pouch: posteromedial wall dilation where gall stones may lodge
Cystic duct
-begins at neck of gall bladder and ends by joining common hepatic duct to form common bile duct
Bile duct
Formed by union of cystic and common hepatic ducts near porta hepatis.
