Liver lobation can be described in different ways, and this PowerPoint uses a three-lobe scheme: the right lobe, the left lobe, and the caudate lobe. The caudate lobe sits on the posterior surface near the IVC and porta hepatis and is functionally distinct enough in its vascular supply and biliary drainage to be treated as its own lobe in some teaching frameworks. Because of that, the slide count often shifts depending on whether the quadrate lobe is grouped with the left lobe or counted separately. In this resource, they’ve grouped the quadrate lobe with the left lobe, yielding three lobes in total. If your course uses the four-lobe model, you’d see right, left, caudate, and quadrate, but for this question the three-lobe interpretation is what’s being tested.
