The left lobe sits in the upper abdomen, crossing a bit into the left side of the chest area. In the common nine-region scheme, it lies mainly in the epigastric region and the left hypochondriac region. This reflects how the liver spans across the midline under the diaphragm, with the left lobe extending into the left upper quadrant. The falciform ligament helps separate the left and right lobes on the liver’s surface, marking this boundary.

So, locating the left lobe in the epigastric and left hypochondriac regions makes sense because the liver as a whole sits high in the abdomen, mostly on the right, but the left lobe reaches into those left-sided upper regions. The right hypochondriac region would correspond to the right lobe, the pelvic cavity is far below the liver, and the umbilical region is central belly-button area, not where the liver primarily resides.
