目的要求
• 一、熟悉肝的功能。
• 二、掌握肝的形态、位置。
• 三、掌握肝外胆道系统。
The liver is the
largest internal organ
of the body, weighs
about 1.3 kg in an
adult.
It is wedge-shaped,
covered by onnective
tissue (Glisson,s
capsule). Its reddish
brown color is due to
its great vascularity.
功能
1、蛋白质、脂类、糖类及维生素等的合成、转化分解
to synthesize ,translate,and breakdown protein,
lipid ,carbohydrate,vitamin,and so on.
2、激素、药物 的转化、解毒
detoxification of chemicals
3、抗体的生成
production of antibody
4、造血
hematopoiesis
5、胆汁的生成
Making bile to help
digestion

Visceral surface
肝肾隐窝(hepatorenal recess)
Visceral surface
has a H-shaped fissures and grooves
-Left limb of H
– Anteriorly: fissure
for ligamentum

肝圆韧带裂
– Posteriorly: fissure

Right limb of H
– Anteriorly: fossa for

– Posteriorly: sulcus

下腔静脉沟
Cross-bar of H is the porta hepatis 肝门:
traversed by
•proper hepatic artery
Connective
•hepatic portal vein
tissue called hepatic pedicle
•Nerves
肝蒂
• right and left hepatic ducts
•lymphatic vessels
Four lobes:
• left
•right
•quadrate
•caudate
Left lobe
caudate

Porta Hepatis肝门:

位置:
Most of liver lies in
the right
hypochondriac region
and epigastric region,
less part extending
into the left
hypochondriac region
Surface projection(体表投影)
• Upper border:
on the right
midclavicular line
it extends the level
of 5th rib
Lower border:
Normally, the right lobe
extends just beneath the
costal margin, it doesn’t
extend beyond the costal
margin;
• In children, compared with
the adult , the liver being
larger in proportion ,it
extends below the costal
arch within in 2cm.
• on the anterior median line
its lower border crosses
3~5cm below the xiphoid
process.
Liver Transplant
• The removal of a diseased liver and replacement
with a healthy liver from a donor who has died. In
some cases, a portion of the liver of a living,
related donor may be used.
肝外胆道
Consists of
• Gallbladder 胆囊
• Left and right hepatic
ducts 肝左、右管
• Common hepatic duct
肝总管
• Common bile duct
胆总管
Obstruction of biliary system
results jaundice in clinical condition.
Gallbladder 胆囊
Position :lies in fossa for
gallbladder on visceral
surface of liver
Gallbladder 胆囊
Four parts
• Fundus of gallbladder
胆囊底
• Body of gallbladder
胆囊体
• Neck of gallbladder
胆囊颈
• Cystic duct
胆囊管
Function: stores and
concentrate bile
Fundus of
gallbladder
(胆囊底)
Surface
projection:
at the junction
of right
midclavicular
line and right
costal arch
Divisions and relations of common bile duct
• Supraduodenal segment
• Retroduodenalsegment
• Pancreatic segment
• Intraduodenal segment
胰头癌时,
为何会发生黄疸?
Intraduodenal
segment
Enters the wall of
descending part of
duodenum obliquely
where jions the
pancreatic duct to
form the
hepatopancreatic
ampulla
opens at the major
duodenal papilla
