Barrel
Barrel (medical term)
Barrel (/bærəl/), in the context of medical terminology, refers to a physical characteristic often used to describe a particular shape or form of the human chest, specifically a chest that appears rounded or bulging, similar to the shape of a barrel. The term is most commonly used in relation to conditions such as Barrel Chest, where the chest appears larger than normal due to long-term over-inflation of the lungs.
Etymology
The term 'barrel' originates from the Old French word 'baril', which refers to a cylindrical container used for storing liquids, particularly wine or beer. The use of the term in a medical context to describe a rounded or bulging chest is a metaphorical extension of this original meaning.
