Digestive System Question


  • Why do farts stink, why do we fart (causes), how do we fart?
A: 
1. Remnants of hydrogen sulfide (gaseous) and skatole contribute to the odour of farts [SULFUR] (ex. eating eggs produces stinky farts due to being rich in sulfur which is derived from bacterial production in guts). 
2. Ingesting too much air (eating/drinking too fast), insoluble food content, unfamiliar or abundant quantity of food causes more frequent farting which is the product of chemical digestive system processes: hydrolisis of carbohydartes and proteins in foods
3. Gases produced in the stomach and intestines from the aforementioned biochemical processes, gas travels up (burp) or down towards rectum and is expelled through anus (FART)
