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.
What else can I help you with?
What are the nonspecific in the immune system?
The body is made up of a specific defense system and nonspecific defense system. The nonspecific defense system is made up of inflammation, fevers, etc. The immune system is part of the specific defense system. This is because the lysosomes in this system bind to specific antigens and have a certain role to carry out. Therefore, there aren't nonspecific defenses in the immune system.
Are the adenoids part of the immune systems?
Yes adenoids are part of immune system. It is the first line of defense.
What is immune response?
An immune response is part of the body's defense against pathogens in which cells of the immune system react to each kind of pathogen with a defense targeted specifically toward that pathogen.
Nina has the flu and a high fever. Her immune system is exhibiting the line of defense. This defense is part of immunity.?

What blood cells are part of the immune system?
White blood cells are part of the immune system's defense. White blood cells flock to irritations and infections to heal or eliminate them.
Does The immune system includes lymphocytes?
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.
What is one non-specific barrier to infection in humans?
The body is made up of a specific defense system and nonspecific defense system. The nonspecific defense system is made up of inflammation, fevers, etc. The immune system is part of the specific defense system. This is because the lysosomes in this system bind to specific antigens and have a certain role to carry out. Therefore, there aren't nonspecific defenses in the immune system.
Why is the skin consider part of the immune system?
Your skin is the first line of defense against pathogens that try to enter the body.
Why do white blood cells need to function?
White blood cells are a key part of your body's defense system and practically control your immune system.
White blood cells are part of the immune system's what?
White blood cells are part of the immune system's defense. White blood cells flock to irritations and infections to heal or eliminate them.
Are lymph nodes in the immune system?
Yes, they are a part of the immune system.
What are the meaning of actigen and antibodies?
Actigen refers to a specific substance that can provoke an immune response, often a part of a pathogen like bacteria or viruses. Antibodies are proteins produced by the immune system in response to antigens; they recognize and bind to specific antigens to neutralize or mark them for destruction by other immune cells. Together, actigens and antibodies play crucial roles in the body’s defense against infections.
