Final answer:
The right intersegmental fissure divides the right lobe of the liver into anterior and posterior segments. There are no true visual intersegmental fissures in the liver like those in the lungs, but the liver's segments can be defined anatomically and functionally. The liver is also attached to the abdominal wall and diaphragm through various ligaments.
Step-by-step explanation:
The right intersegmental fissure divides the right lobe of the liver into an anterior and a posterior segment. The anatomy of the liver is quite complex, consisting of two primary lobes which are further divided into smaller functional units.
It is important to note that, unlike the lungs which have lobes and segments defined by fissures, the liver does not contain true intersegmental fissures visually dividing it in the way the lungs are divided. However, anatomically and functionally, the liver can be divided into distinct segments.
The liver's connection to the abdominal wall and the diaphragm is enabled by five peritoneal folds known as ligaments. Among these are the falciform ligament and the ligamentum teres hepatis, which are the remnants of the umbilical vein that separate the right and left lobes anteriorly. The lesser omentum attaches the liver to the lesser curvature of the stomach.
