Functional Anatomy of the Liver

Peritoneal Attachments

The liver is connected to the abdominal wall and diaphragm by five peritoneal folds referred to as ligaments. These are the falciform ligament, the coronary ligament, two lateral ligaments, and the ligamentum teres hepatis.

The falciform ligament is not of embryological origin although some publications describe this as a remnant of ventral messengers of the foetus, but is more accurately described as a peritoneal reflection of the upper abdominal wall. It extends rom the umbilicus to the liver and has the ligamentum teres of the liver on its free edge. It is somewhat to the right of the midline.

The coronary ligament is formed by the peritoneal reflection from the diaphragm to the liver which has two layers and meet on the right.

Right and left triangular ligaments are lateral ligaments on the lateral aspects of each lobe respectively.

The ligamentum teres also sometimes called the round ligament of the liver is the obliterated remains of the left umbilical vein. In utero the left umbilical vein brings blood from the placenta back into fetus.

The ligamentum venosum is the fibrous remnant of the fetal ductus venous which shunts oxygenated blood from the left umbilical vein to the IVC – bypassing the liver.
