Fig. 213. The origin of the Peritoneal Ligaments connected with the Liver

When the liver grows out from the septum transversum it withdraws within the ventral mesentery. Out of the ventral mesentery are formed all the ligaments of the liver (Fig. 213 A). These are the following:

1. The Gastro-hepatic Omentum is that part of the ventral mesentery which passes from (1) the oesophagus, (2) lesser curvature or ventral border of stomach, and (3) first stage of duodenum to (1) the diaphragm, (2) the posterior part of the longitudinal fissure of the liver, the ductus venosus lying within its hepatic attachment, and (3) the transverse fissure of the liver (Fig. 213 B). The portal and umbilical veins lie in the ventral mesentery (Fig. 213^4); the hepatic artery passes by it to the liver. The right or free border of the gastro-hepatic omentum, with the falciform ligament containing the remnant of the umbilical vein, represents the posterior border of the primitive ventral mesentery (Fig. 213 A).

2. The Falciform Ligament, containing the umbilical vein, also represents part of the ventral mesentery (Fig. 213 A). At an early stage the umbilical veins reached the sinus venosus by passing through the septum transversum. The development of the liver led to its being thrust out within the falciform ligament.

3. The coronary, the right and left lateral ligaments, and the attachments to the vena cava and diaphragm (Fig. 213 5) are developed as the liver emerges from the septum transversum, and separates itself from the diaphragm.
