During health class a student asks the school nurse how come flatus smells. What would be the nurse's best response?
A) Intestinal bacteria form chemicals that cause odor. Gas is also formed. Among the gases formed are hydrogen sulfide and ammonia, and they are expelled from the body as flatus.
B) Intestinal bacteria form chemicals that make our stool smell.
C) By the time we expel flatus from our rectum it has picked up all the bad smells from what is in our intestines.
D) Flatus doesn't smell until it hits the air.
Ans: A
Feedback: Chemicals formed by intestinal bacteria are responsible in large part for the fecal odor. Gases formed contain methane, hydrogen sulfide, and ammonia, among others. The GI tract normally contains approximately 150 mL of these gases, which are either absorbed into the portal circulation and detoxified by the liver or expelled from the rectum as flatus. This makes options C and D incorrect. Option B is incorrect because it does not answer the question.
