Nonspecific protective mechanisms repel all microorganisms equally , while the specific immune responses are tailored to particular types of invaders. ... These immune mechanisms also help eliminate abnormal cells of the body that can develop into cancer.
What is considered a nonspecific 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 are some examples of specific and nonspecific immune responses?
| Line of Defense Examples | Innate (non-specific) First Skin, hair, cough, mucous membranes, phagocytes, granulocytes | Adaptive (specific) Second Pus, swelling, redness, pain, T and B lymphocyte response |
|---|
Which is an example of a specific immune response?
An organ-specific disease is one in which an immune response is directed toward antigens in a single organ. Examples are Addison disease , in which autoantibodies attack the adrenal cortex, and myasthenia gravis, in which they attack neuromuscular cells.
What are the two types of specific immunity?
There are two types of immunity: active and passive .
How does the immune system provide an immediate nonspecific response?
The immune system protects from infection with layered defenses of increasing specificity. Physical barriers prevent pathogens from entering the organism. If these barriers are breached , the innate immune system provides an immediate, non-specific response.
What are three types of nonspecific immunity?
NON SPECIFIC DEFENSES: Skin and Mucous membranes, antimicrobial chemicals , natural killer cells, phagocytosis, inflammation and fever. b. “constant” region (the stem) – determins the cells and chemicals an antibody can bind to, and how that class of antibody will function.
What is a specific response in the immune system?
Specific immune responses are triggered by antigens . Antigens are usually found on the surface of pathogens and are unique to that particular pathogen. The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies.
What is the 1st 2nd and 3rd line of defense?
In the Three Lines of Defense model, management control is the first line of defense in risk management, the various risk control and compliance over- sight functions established by management are the second line of defense, and independent assurance is the third.
Which line of defense is most important?
The Body's MOST IMPORTANT Nonspecific Defense is the SKIN . UNBROKEN Skin provides a continuous layer that protects almost the whole body. Very Few Pathogens can penetrate the layers of dead cells at the skin's surface.
What are the steps of the immune response?
The cellular immune response consists of three phases: cognitive, activation, and effector . In the cognitive phase, macrophages display foreign antigens on their surface in a form that can be recognized by antigen-specific T H 1 (T helper 1) lymphocytes.
What are the 4 types of immunity?
- Innate immunity: Everyone is born with innate (or natural) immunity, a type of general protection. ...
- Adaptive immunity: Adaptive (or active) immunity develops throughout our lives. ...
- Passive immunity: Passive immunity is “borrowed” from another source and it lasts for a short time.
What are 5 examples of nonspecific immunity?
Nonspecific defenses include anatomic barriers, inhibitors, phagocytosis, fever, inflammation, and IFN .
What does specific immunity include?
Acquired immunity is also called specific immunity because it tailors its attack to a specific antigen previously encountered. Its hallmarks are its ability to learn, adapt, and remember . Acquired immunity takes time to develop after first exposure to a new antigen.
Which type of immune system has an immediate maximal response?
| Table 1. Components of the immune system | Innate immune system Adaptive immune system | Exposure leads to immediate maximal response Lag time between exposure and maximal response | Cell-mediated and humoral components Cell-mediated and humoral components |

What are 2 types of nonspecific 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.
