The bodies first defence against a virus is your skin. The body first defense against a virus is Mucus. Mucus
I Believe it is a chemical barrier because is contains an enzyme called "lysozyme" which prevents pathogens entering the human body.
As with all mucus in the body, its a lubricant to keep the lungs moist, prevents the lung lining from sticking to itself and prevents foreign body's like bacterium and dust from in bedding into the lungs causing infection.
In the digestive system, mucus is used as a lubricant for materials which must pass over membranes. A layer of mucus along the inner walls of the stomach is vital to protect the cell linings from the highly acidic environment within it.
Nonspecific like the skin, mucous membranes, tears, mucus and the inflammatory response... are designed with and acidic surface that, for the most part, repels bacteria and are attributable to factors other than specific antibodies. They are often called innate immunities. Specific immunity has to do with how our lymphocytes (specialized white blood cells, such as B and T Cells) that can remember a specific virus or bacteria, and the next time it shows up, there's a whole welcoming party ready with lots of demolition gear to destroy the unwelcome guests.
Your body's most important nonspecific defense is the skin. Other nonspecific defenses include mucus, sweat, and tears.
Mucus, sweat, and tears
Yes, the skin is the most important nonspecific defense. This is because your oil and sweat glands are acidic.
Mucus that are present in body contains macrophages and phagocytes and it acts as first line of defense in our immune system.
The first line of immune defense is the skin and mucus membranes. Skin acts as a physical barrior, blocking pathogens from entering. Mucus wihin the nasal cavity blocks some of the pathogens from entering the body. Cilia also aid in protectiong by acting as a barrior as well. There is also mucus lining the bronchial tubes, which like other mucus, blocks pathogens.
tears and mucus
Mucus.
The respiratory system has a number of nonspecific defenses against disease. The hairs of the nose trap dust and pathogens. Mucus in the upper and lower respiratory system traps foreign bodies and pathogens. The cilia constantly move the mucus with this trapped material out of the system. The cough and sneeze reflexes also offer protection.
mucus membranes

Pathogens are every where. You are breathing them in right now but the mucus in your lungs is preventing you getting ill.
it has mucus.
