Lobe (anatomy)

For other uses, see Lobe (disambiguation).

In anatomy, a lobe is a clear anatomical division or extension of an organ (as seen for example in the brain, lung, liver, or kidney) that can be determined without the use of a microscope at the gross anatomy level. This is in contrast to the much smaller lobule, which is a clear division only visible under the microscope.

Interlobar ducts connect lobes and interlobular ducts connect lobules.
