Final answer:
The liver is surrounded by a membrane called the peritoneum and ligaments such as the falciform ligament. These structures hold the liver in place and divide its lobes, while the lesser omentum connects the liver to the stomach.
Step-by-step explanation:
If you were to look at a person's liver, that organ would be surrounded by a membrane known as the peritoneum and peritoneal folds referred to as ligaments. The liver's structure involves a large right lobe and a smaller left lobe, with further subdivisions in the right lobe identifying an inferior quadrate lobe and a posterior caudate lobe. It is attached to the abdominal wall and diaphragm via five such ligaments: the falciform ligament, the coronary ligament, two lateral ligaments, and the ligamentum teres hepatis. The falciform ligament, as well as the ligamentum teres hepatis, are remnants of the umbilical vein and divide the right and left lobes at the front. Furthermore, the liver's connection to the abdominal area is maintained by the lesser omentum which tethers the liver to the lesser curvature of the stomach.
