bowel: [13] Bowel comes via Old French buel or bouel from Latin botellus ‘small intestine, sausage’, a diminutive form of botulus ‘sausage’. The term botulism ‘food poisoning’ was coined on the basis that the toxin responsible for it was originally found in sausages and other preserved meats. => botulism[bowel etymology, bowel origin, 英语词源]
