bowel
[C/U] Both
pl: bowels
This term carries a heavy clinical or anatomical weight, often evoking a sense of internal vulnerability or biological necessity. While it describes a physical organ, it is frequently used in medical contexts to discuss health, dysfunction, or surgical procedures. In a non-medical sense, it often appears in archaic or literary contexts to describe the deepest part of one's being or the seat of intense emotion. Using this word in casual conversation typically signals a shift toward a frank, biological discussion of digestion or a very formal medical report.
Countable when referring to the individual tubes of the digestive tract (small and large bowels). Uncountable when referring to the general anatomical region or the function of the gut.
