What are some functions of the gut microbiome? - ANSWER-•Supports digestion •support epithelial homeostasis in the gut •Protect against pathogens •Facilitate development of the immune system •Functions as a multifunctional organ that provides metabolic traits not fully evolved in our genome: break down of plant polysaccharides, transformation of conjugated bile acids, synthesis of certain vitamins (i.e. vitamin K) •Postnatal colonization educates immune system so we become tol...
