Physical barriers preventing diseases include skin, mucous membranes, microbiome, low stomach pH, blood proteins, urination, and tightly joined endothelial cells lining blood vessels. The body also has external physical barriers like keratin and hair.
Physical barriers that help prevent an individual from contracting diseases include the skin, mucous membranes, and microbiome. The skin acts as a continuous barrier to infectious pathogens and destroys them through desiccation and acidity.
Mucous membranes, found in regions of the body not protected by skin like eyes and mouth, have defense mechanisms such as tears and mucus secretions that trap and eliminate the pathogens. The microbiome, beneficial microorganisms that coexist on the skin and in the gut, compete with invading pathogens, preventing infection. Other basic defense mechanisms include low stomach pH, blood proteins, and the process of urination.
At the cellular level, tightly joined cells prevent invaders from crossing to deeper tissues. For example, endothelial cells that line blood vessels have tight cell-to-cell junctions that block pathogens from entering the bloodstream.
Lastly, the body has significant external physical barriers, like the protein keratin and hair in body openings, which physically trap pathogens and stop their movement deeper into the body.
