lobe
Plural
lobes
1
(anatomy) a rounded part of an organ, such as, lungs or brain that seems to be separate in some way from the rest
A lobe refers to a distinct and often rounded subdivision or projection of an organ or structure. Lobes can be found in various organs, such as the brain, lungs, liver, and ears. They are typically demarcated by anatomical landmarks or divisions and serve specific functions within the organ they belong to. For example, in the brain, the cerebral hemispheres are divided into frontal, parietal, temporal, and occipital lobes, each associated with different cognitive and sensory functions. Similarly, in the lungs, lobes are responsible for the exchange of gases and are further divided into lobules. Lobes play a vital role in the organization, function, and specialization of different organs, contributing to the overall complexity and efficiency of the human body.
