Tears contain an antibacterial substance :)
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
Yes, lysozyme is found in saliva and tears and acts as a defense mechanism by breaking down the cell walls of bacteria, thereby helping to protect the body against infection.
Tears primarily serve to lubricate and protect the eyes, as well as to remove irritants. They are not considered a primary defense system, as they do not actively target pathogens or foreign substances in the body. However, tears do contain enzymes that can help fight certain types of bacteria.
You have the enzyme called as lysozyme. It is the enzyme that act as a bacteriostatic substance. It adversely affect the bacteria on the surface of the eye.
tears are 5.0 blood is 7.4 but the both can kill bacteria. with the acid in them.

Yes
destroy bacteria
Tears contain lysozyme, an enzyme that can help kill bacteria by breaking down their cell walls. Additionally, tears contain other antimicrobial proteins and antibodies that can help protect the eyes from infections.
Tears produce lysozyme to kill bacteria, gastric juice secretes Hcl that kills bacteria.
