"<p>The intestinal barrier protects against toxins and pathogens from entering the bloodstream from inside the intestine. The intestinal barrier includes those intestinal bacteria that prevent pathogenic bacteria from colonising. Furthermore, the thick layer of mucus formed by mucosal cells in the intestine protects the intestine against pathogens. Tight junctions between the mucosal cells provide a tight barrier against toxins or pathogens. The immune defence cells located in the intestinal wall are also part of the intestinal barrier.</p>\n"
