Explanation:
The skin, tears and stomach acid are nonspecific defenses and they are some of the examples of the body's first line of defense. Nonspecific defenses are made up of interferons, chemical barriers (e.g. tears and stomach acid), inflammation and physical barrier (e.g. skin).
These nonspecific defenses defend the body from pathogens through their chemical contents in the body fluid or the tissue.
For example, Stomach acid is made of hydrochloric acid (HCl), HCl is potent enough to destroy pathogens that make its way into the stomach through food; this kind of barrier is a chemical barrier.
So also, the skin is a physical barrier which serve as a defense against pathogens.
