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
Is lysozyme in saliva and tears to destroy bacteria a body defense?
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.

What is the process by which immune cells engulf and then destroy bacteria known as?
The process by which immune cells engulf and destroy bacteria is called phagocytosis. This involves the immune cell recognizing the bacteria as foreign, engulfing it into a membrane-bound vesicle called a phagosome, and then fusing the phagosome with lysosomes containing enzymes to destroy the bacteria.
Which is found in tears that damages bacteria by attacking the cell walls?
Lysozyme
