Explain the role of the intestinal microbiota in the maintenance of health
What will be an ideal response?
The intestinal microbiota help maintain health in a variety of ways:
(1 ) The billions of microbes in the gastrointestinal tract outcompete pathogens in a process called microbial antagonism. (2 ) The normal microbiota can feed on the partially digested or indigestible contents of the colon, and even though this produces some undesirable by-products such as flatus, this is overall a beneficial process for the host. (3 ) Many intestinal microbes produce important vitamins for the host, such as vitamin K, B12, folic acid, and biotin.
