skin and mucous membranes first line of defense second line-leukocytes and macrophages, inflammation and fever third is immune system

Your body's third line of defense is specific defenses, such as the immune response.
Yes adenoids are part of immune system. It is the first line of defense.
In the immune system, the first line of defense are mechanical and physical barriers, such as the skin and the cornea of the eye. The main line of defense, meanwhile, are the innate immunity and acquired immunity of an organism.
Your skin,sweat,mucus,and tears is the first line of defense of your immune system. it is the original protector from bacteria and viruses
The third line of defence against pathogens is called the Specific Immune Responce
1- the immune systems helps fight off diseases 2-your skin is the first line of defense for your immune system. hope that helps!:)
The Second Line of defense is mainly called the Inflammatory Response. Some may say the immune response is the second layer too. The Second Line of Defense also includes leukocytes such as macrophages.

Generally, no because they include t and b cells which are part of the 3rd line of defense. But there are specific cell types, that are lymphocytes that are considered part of one's innate immune response (2nd line of defense). These are gamma delta T cells, which are involved in the early phages of an immune response.
The human immune system can be separated into three "lines of defense" 1) Tthe first line includes physical barriers-primarily the skin, and biochemical barriers-mucous, sweat, stomach acids, wax, oil ect. This is considered a non-specific response because the response is not different for different pathogens. 2) The second line includes the inflammatory response, natural killer cells, macrophages, and fever. This level of defense is also considered non-specific. 3) The third line includes the two specific defenses-your humoral or antibody mediated immune response and your cell mediated immune response. In both cases your body is responding to a particular antigen or infectious agent.
