The story of the word

The gym word is a clipping of cardiovascular, itself Greek bolted to Latin. Kardía covered more than the pump: it was the seat of feeling and also the mouth of the stomach, which is why heartburn has nothing to do with the heart and why anatomists still call that opening the cardia. Doctors kept the long form. Everyone else took the first two syllables.
