What is a specific immune response?
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..
How does the specific immune response work?
Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.
What are examples of specific immune responses?
The Innate vs. Adaptive Immune ResponseLine of DefenseExamplesInnate (non-specific)FirstSkin, hair, cough, mucous membranes, phagocytes, granulocytesAdaptive (specific)SecondPus, swelling, redness, pain, T and B lymphocyte response
What are B cells and T cells?
T cells and B cells T cells (thymus cells) and B cells (bone marrow- or bursa-derived cells) are the major cellular components of the adaptive immune response. T cells are involved in cell-mediated immunity, whereas B cells are primarily responsible for humoral immunity (relating to antibodies).
What are the 4 types of adaptive immunity?
naturally acquired active immunity. naturally acquired passive immunity. artificially acquired active immunity.
What are the steps of the inflammatory response?
The response to ICH occurs in four distinct phases: (1) initial tissue damage and local activation of inflammatory factors, (2) inflammation-driven breakdown of the blood–brain barrier, (3) recruitment of circulating inflammatory cells and subsequent secondary immunopathology, and (4) engagement of tissue repair …
Which line of defense is most important?
The third line of defense is most important because it involves the cells and proteins of adaptive immunity, responding directly to specific antigens. All three lines of defense depend on each other to function properly and no single line is more important than the other.
What are the two types of lymphocytes involved in adaptive immune responses?
B cells and T cells are the major types of lymphocytes involved in adaptive immunity. B and T cells can create memory cells to defend against future attacks by the same pathogen by mounting a stronger and faster adaptive immune response against that pathogen before it can even cause symptoms of infection.
What are the two types of adaptive immunity and what types of microbes do these adaptive immune responses combat?
The two types of adaptive immunity are cell-mediated immunity and humoral immunity. Cell-mediated immunity, mediated by T cells, is essential for protection against intracellular pathogens. … T lymphocytes express the T cell antigen receptor and either CD4 or CD8 and mediate cell-mediated immune responses.
What is the 1st 2nd and 3rd line of defense?
The first line of defense are the physical and chemical barriers, which are considered functions of innate immunity. … The third line of defense is specific resistance, which is considered a function of acquired immunity.
How long does it take for the adaptive immune system to respond?
In humans, it takes 4-7 days for the adaptive immune system to mount a significant response.
What are the two types of specific immune responses?
There are two broad classes of such responses—antibody responses and cell-mediated immune responses, and they are carried out by different classes of lymphocytes, called B cells and T cells, respectively. In antibody responses, B cells are activated to secrete antibodies, which are proteins called immunoglobulins.

What triggers the adaptive immune system?
Adaptive immunity is an immunity that occurs after exposure to an antigen either from a pathogen or a vaccination. This part of the immune system is activated when the innate immune response is insufficient to control an infection.
What is the first immune response?
Conclusion. Innate immunity is the first immunological, non-specific mechanism for fighting against infections. This immune response is rapid, occurring minutes or hours after aggression and is mediated by numerous cells including phagocytes, mast cells, basophils and eosinophils, as well as the complement system.
