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 does an epidermal cell do?
The two main functions of the epidermis (or the skin) are: 1) A barrier against pathogens and toxins. - The epidermis acts as a physical barrier but also as a chemical barrier due to the presence of lipids and acids which work to destroy certain pathogens. 2) Hydration - The skin holds a large percentage of water and lipids arranged within the epidermis act as a barrier to prevent water loss from the body.
What is the strong mechanical barrier that resists penetracted from pathogens?
skins
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.
What organ system is a waterproof barrier that blocks the entrance of pathogens?
The skin is the largest organ and forms an effective barrier.
Is the integumentary system the second and third line of defense against infection?
The integumentary system is one of the first lines of defense against infection. It provides a physical and chemical barrier against the entry of pathogens.
What structures provide physical or chemical barriers against microbial invasion?
The skin and mucous membranes provide living things with physical and chemical barriers against invasion of microbes. These membranes are part of the immune system.
How are stomach acid and mucous as a defense against pathogen?
Stomach acid is a chemical barrier against pathogens. The low pH of the acid creates an environment in which pathogens are unable to survive and will often kill them. Mucous is a physical barrier against pathogens. It acts to trap pathogens to prevent them from entering the body any farther.
What organ is your first line of defense against pathogens?
The integumentary system (skin) and mucous membranes are the first line of defense. They provide a physical barrier against invasion of pathogens. Any break in this physical barrier, such as a cut, makes it easier for pathogens to enter your body.
Is mucus a chemical barrier and if so why?
I Believe it is a chemical barrier because is contains an enzyme called "lysozyme" which prevents pathogens entering the human body.
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.

This enzyme is also found in your saliva.
Is the tear duct a physical barrier or a chemical barrier?
it is a chemical barrier because it produces tears that are chemicals. also- for your information, skin is a physical barrier along with the nose and mucus and cilia. sebum and stomach acid are chemical. :D

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 is one way skin helps protect the body from infection?
Serves as a physical barrier to keep pathogens out.
Beneficial microorganisms found in the body that help create a barrier against pathogens are known as?
normal flora
What is the primary function of integumentary system?
The integumentary system acts as a defense barrier against pathogens and keeps them out!
