The body's first line of defense against pathogens uses mostly physical and chemical barriers such as sweat, skin, tears, mucus, stomach acid, and so on. Our skin and other membranes which line the body passages are fairly effective in keeping most pathogens out of the body. Mucus can trap pathogens, which are then washed away or destroyed by chemicals. Tears, sweat, and saliva all contain chemicals to destroy pathogens to some extent.
There's multiple ways to organize the body's defenses. One way splits them into two parts: specific and nonspecific. Specific, also known as adaptive, is the last line of defense. This describes anything that targets the specific antigen, and not foreign substances in general. Specific includes lymphocytes, their antibodies, and the rather complex system that allows your body to become immune to certain invaders.
The non-specific, or innate, immune system is the first line. This includes the first line of defense as described in the first paragraph, but also includes non-specific cells such as macrophages and neutrophils, which will eat and destroy just about anything it encounters that isn't a part of your body. Also included are the complement system, inflammatory response and interferons, which are left for another question.

What is the first line of Mitch's non-specific defenses?
The first line of Mitch's non-specific defenses is the physical barriers provided by the skin and mucous membranes. These barriers serve as the body's first line of defense against pathogens by preventing their entry into the body.
How does the body's first line of defense function?
The Body's first line defense acts as physical barriers, in which it functions by trapping the pathogens and blocking them from entering the body. Also, all first line defenses act the same way to all pathogens, in which they're called non-specific defense.
Which of these is not a part of the body's first line of defense?

What are the parts involved in the body's first line of defense?
white blood cells
What level of prevention is a vaccine?
there are actually three categories of defenses in the body, namely: first line of defense, second line of defense and the third line of defense.first line of defense is our skin. the vaccine you're talking about falls under the second line of defense because it involves the immune system wherein these vaccines were introduced into the body,nonetheless, the cells on our body creates/secretes chemicals that serve as defense mechanism; and the third line of defense is the use of medications or chemicals prescribed by the doctors.
What are the four components of the body first line of defense?
skin, mucus, tears, and sweat.
When does the bodys second line of defense come into play?
The body's second line of defense, which includes inflammatory responses and phagocytic cells, comes into play when pathogens manage to breach the first line of defense (skin and mucous membranes). These responses help contain and eliminate the pathogens before they can cause harm.
How does the body fight the measles?
