What in tears act as a chemical barrier and destroy pathogens on the surface of the eye?
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.
Is tears a chemical barrier against pathogens?
yes, tears prevent pathogens from entering the eye. when an irritation occurs the eye produces a salty liquid (tears) to clean the eye from any dust or pathogens. eyelashes also prevent pathogens and dust from entering. In terms of a chemical barrier, your tears contain the enzyme lysozyme which can disrupt the cell walls of gram-positive bacteria by digesting the peptidoglycan in them. This enzyme is also found in your saliva.
What is the strong mechanical barrier that resists penetracted from pathogens?
skins
What organ system is a waterproof barrier that blocks the entrance of pathogens?
The skin is the largest organ and forms an effective barrier.
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.

Can an intact skin surface be the best way the body can defend itself against pathogens?
1) Physical barrier. 2) "Normal bacteria" will resist new-comers.
What organ system is a waterproof barrier that blocks the entrance of pathogens?
The skin is the largest organ and forms an effective barrier.
What does the sebum do for the immune system?
Sebum, an oily substance produced by the sebaceous glands in the skin, can help protect the skin and hair follicles from harmful microbes. It has antimicrobial properties that can help fight off bacteria and fungi, thus supporting the immune system's defense against infections.

Which organ system is used as a waterproff barrier that blocks the entrance of pathogens into the body and loss of water from the body?
The integumentary system is used as a waterproof barrier that blocks the entrance of pathogens into and prevents water loss from the body.
Which system is waterproof barrier that blocks the entrance of pathogens?
Integumentary system (skin)
What protects mucosal barriers?
Mucosal barriers are protected by various mechanisms such as mucus production, antimicrobial peptides, IgA antibodies, and the presence of commensal bacteria that compete with pathogens for nutrients and space. Additionally, immune cells located within the mucosa work to detect and eliminate invading pathogens to maintain barrier function.
What is the body first line of defense against bacteria and viruses?
saliva, mucus, hairs and Skin
What features of the epidermis prevent the entry of pathogens?
The epidermis otherwise known as the outer layer of skin, has many unique ways of keeping pathogens from entering your body. For example, your skin is like the cover to your car, this way your cause doesn't get dirty. But your skin does this in a very different way. Even though it has many small openings none as pores, these pores are filled with good bacteria, that which when recognize a foreign entity will attack. Also your skin has oil covering it, this slows the pathogens/bacteria down which they then die in. Your skin also has sweat, and yes, the sweat is meant to give off heat, but it is also to drown pathogens/bacteria and it also is somewhat acidic, also helping in the destruction of the pathogens/bacteria. Now another, usually over seen way of protection, is your hair, some people who are very hair, somewhat have a barrier against things such as mosquitoes.
