THE LIVER. 187 
Trace the peritoneal connections as follows: 
The lesser omentum, represented by the hepatoduodenal 
ligament and the hepatogastric omentum, previously 
divided. 
The falciform ligament (lig. falciforme hepatis), a broad 
median sheet connecting the anterior surface of the liver 
with the diaphragm and extending backward to the ventral 
abdominal wall. The position of this ligament indicates the 
line of division of the liver into right and left lobes. The 
free arcuate border of the ligament contains a thin cord, the 
round ligament (lig. teres hepatis), which marks the 
position of the umbilical vein in the foetus. The corres- 
ponding umbilical notch is less conspicuous than in man 
because of the highly lobulated condition of the whole organ 
in the rabbit. 
The coronary ligament (lig. coronarium hepatis), a short 
circular fold, continuous with the falciform, and connecting 
the anterior surface of the liver with the middle of the 
diaphragm. 
The left triangular ligament (lig. triangulare sinistrum), a 
lateral continuation of the coronary connecting the left lobe 
with the diaphragm. 
3. Trace the branches of the common bile duct, the hepatic 
artery and the portal vein. These structures traverse the lesser 
omentum side by side and their branches are similarly arranged. 
(a) 
The common bile duct (d. choledochus) is formed on the 
posterior surface of the liver by the union of a left hepatic 
duct (d. hepaticus) with a similar duct from the right 
anterior lobule. The latter receives the cystic duct (d. 
cysticus) from the gall bladder. Special ducts from the 
right posterior lobule and from the caudate lobe enter the 
common bile duct through a short common trunk. The 
common bile duct passes backward on the right side of the 
portal vein, and enters the digestive tube on the dorsal 
surface of the first (superior) portion of the duodenum 
(b) 
immediately beyond the pylorus. 
The hepatic artery (a. hepatica) approaches the liver by 
passing forward on the right side of the portal vein ventral to
