Final answer:
The upper part of the abdominal cavity with more than one lobe is the liver, which has a right lobe, a left lobe, and additional smaller lobes.
Step-by-step explanation:
The upper part of the abdominal cavity with more than one lobe that you are referring to is the liver. The liver is an essential organ divided into two primary lobes: a larger right lobe and a smaller left lobe. Some anatomists also recognize additional lobes in the liver, such as the quadrate lobe and the caudate lobe, which contribute to its lobular structure. The liver's lobes are held in place and connected to other structures by several ligaments, including the falciform and the coronary ligaments.
