A "lobe" refers to a rounded or projecting part of an organ or structure in the body. In the human brain, for example, there are four main lobes: the frontal lobe, parietal lobe, temporal lobe, and occipital lobe. Each lobe has specific functions, such as processing sensory information, controlling movement, and managing emotions. In addition to the brain, lobes can also be found in other organs, such as the lungs, which have lobes that help facilitate breathing. The liver also has lobes that play a role in digestion and metabolism. Overall, lobes are important components of various biological systems.
