Your tears contain the enzyme lysozyme. This enzyme acts by disrupting the cell-walls of gram-positive bacteria by digesting the peptidoglycan in them, thereby preventing infection.
This enzyme is also found in your saliva and is an example of a non-specific immune response.

How do tears fight against pathogens?
True A+
Tears contain antibacterial substances that destroy many bacteria?
Basic a level knowledge: Tears are a form of chemical barrier from infection. The enzyme lysozyme is found in tears which kills of some bacteria which helps prevent pathogens entering the body and causing infection. I hope this helps, I'm unsure how the enzyme kills the bacteria as I was only aware that enzymes are catalysts that lower the activation energy in a reaction. If any one knows I'll be very grateful. :) Xxx

What are chemicals produced by the body that attack invading germs?
Enzymes in body fluids provide a chemical barrier to pathogens. Gastric juice, for example, contains the protein-splitting enzyme pepsin and has a low pH due to hydrochloric acid in the stomach. The combined effect of pepsin and hydrochloric acid kills many pathogens that enter the stomach. Similarly, tears contain the enzyme lysozyme, which destroys certain bacteria on the eyes. The accumulation of salt from perspiration also kills certain bacteria on the skin.
