Various mechanical and chemical barriers exist that prevent pathogens from entering the body: The respiratory tract contains cells that sweep and trap particles up into the throat where they exit the body; Mucus Chemical enzymes The stomach has a(n) acidic pH which inhibits the growth of bacteria; Bacteria that typically reside in the large intestine, vagina, mouth, and other body parts prevent pathogens from taking up residence; Cilia Oil gland secretions contain chemicals that weaken pathogens on the skin:
