nonspecific immunity are things that protect the body from various bacterias, viruses, and pathogens. ... Specific immunity are things that protect the body from specific pathogens. It includes the third line of defense. They include the lymphocytes (white blood cells) such as the macrophages, t cells, and memory b cells.
What is the difference between specific and non specific responses?
Specific immune response is generated for a particular pathogen while nonspecific immune response is common for all types of pathogens. Thus, the main difference between specific and nonspecific immune response is the specificity of the immune response towards the pathogen.
What is the differences between natural immune response and specific immune response?
The first line of defense against non-self pathogens is the innate, or non-specific, immune response. The innate immune response consists of physical, chemical and cellular defenses against pathogens. ... The adaptive immune response is specific to the pathogen presented.
What is non specific immune response?
The non-specific response is a generalized response to pathogen infections involving the use of several white blood cells and plasma proteins. Non-specific immunity, or innate immunity, is the immune system with which you were born, made up of phagocytes and barriers.
What is a specific immune response?
Specific immune responses are triggered by antigens. ... The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies. Antibodies attach to an antigen and attract cells that will engulf and destroy the pathogen.
What are two types of non specific immunity?
there are two types: nonspecific, innate immunity and specific, acquired immunity. Innate immunity, with which an organism is born, involves protective factors, such as interferon, and cells, such as macrophages, granulocytes, and natural killer cells, and its action does not depend on prior exposure to a pathogen.
What are the two types of specific immunity?
Antibodies are disease-specific. For example, measles antibody will protect a person who is exposed to measles disease, but will have no effect if he or she is exposed to mumps. There are two types of immunity: active and passive.
What are different types of immune cell?
The cells of the immune system can be categorized as lymphocytes (T-cells, B-cells and NK cells), neutrophils, and monocytes/macrophages. These are all types of white blood cells. The major proteins of the immune system are predominantly signaling proteins (often called cytokines), antibodies, and complement proteins.
What are the steps of immune response?
The normal immune response can be broken down into four main components: pathogen recognition by cells of the innate immune system, with cytokine release, complement activation and phagocytosis of antigens. the innate immune system triggers an acute inflammatory response to contain the infection.
What are the components of immune system?
The immune system is made up of special organs, cells and chemicals that fight infection (microbes). The main parts of the immune system are: white blood cells, antibodies, the complement system, the lymphatic system, the spleen, the thymus, and the bone marrow.
What are three types of nonspecific immunity?
Some nonspecific defenses exist independently of infection (e.g., genetic factors, anatomic barriers, nonspecific inhibitors in body fluids, and phagocytosis). Others (e.g., fever, inflammation, and interferon) are produced by the host in response to infection.

What are non specific Defences of the human body?
Nonspecific defenses include physical and chemical barriers, the inflammatory response, and interferons. Physical barriers include the intact skin and mucous membranes. These barriers are aided by various antimicrobial chemicals in tissue and fluids.
