Question

Quizplus · Accepted Answer

Intestinal flora refers to the microorganisms (primarily bacteria) that inhabit our digestive tract. Parasites are not typically considered part of the natural intestinal flora, though they can be present in some cases as a result of infection. Fibre is a type of nutrient that aids in digestion but is not a living organism. Probiotics are live microorganisms that can be consumed to improve the balance of the existing intestinal flora, but they are not the primary constituents of the intestinal flora itself.
