What are some examples of natural barriers in the immune system?
White blood cells, mucous membranes, and stomach acid
True or false: B cells eliminate infected or cancerous cells.
False
True or false: Stomach acid is a natural barrier of the immune system.
True
Which type of immunity is responsible for cell-mediated immunity?
Acquired immunity
Which type of white blood cell destroys invaders and infected cells?
T lymphocytes
True or false: Phagocytes and lymphocytes are not important in the immune system.
False
True or false: T cells are responsible for antibody-mediated immunity.
False
What do B lymphocytes do in the immune system?
Produce antibodies
What is an example of artificially acquired active immunity?
Vaccination
True or false: B lymphocytes destroy invaders and infected cells.
False
True or false: Vaccination is an example of naturally acquired active immunity.
False
True or false: Immunoglobulins are carbohydrate molecules produced by plasma cells.
False
True or false: Antibodies are produced by T lymphocytes.
False
Which organs are considered primary lymphoid organs in the immune system?
Bone marrow and thymus
What are immunoglobulins?
Glycoprotein molecules produced by plasma cells
True or false: There are three types of immunoglobulins: IgG, IgM, and IgE.
False
How many types of immunoglobulins are there?
5
What is the difference between active and passive immunity?
Active immunity is acquired through vaccination or exposure to a pathogen, while passive immunity is acquired through the transfer of antibodies from another source
True or false: The bone marrow is a secondary lymphoid organ.
False
Which immunoglobulin is the major one in blood and a key player in the immune response?
IgG
True or false: Passive immunity is long-lasting.
False
True or false: IgM is the major immunoglobulin in blood and a key player in the immune response.
False
Which type of immunity is present from birth and does not require prior exposure to a pathogen?
Innate immunity
What are the two types of immune responses in the adaptive immune system?
Cell-mediated and humoral
True or false: Humans only have one type of immunity.
False
Which type of white blood cell engulfs and digests pathogens in the immune system?
Phagocytes
True or false: The humoral immune response is part of the innate immune system.
False
What do antibodies do in the immune system?
Lock onto specific antigens to prevent future attacks
True or false: The cell-mediated immune response is part of the adaptive immune system.
True
Study Notes
- The immune system defends the body against infections and foreign substances.
- The immune system has three lines of defense: physical and chemical barriers, non-specific innate responses, and specific adaptive responses.
- Natural barriers include the skin, mucous membranes, tears, earwax, mucus, and stomach acid.
- White blood cells, including phagocytes and lymphocytes, play a key role in the immune system.
- B lymphocytes find targets and send defenses, while T lymphocytes destroy invaders and infected cells.
- Antibodies are produced by B lymphocytes and lock onto specific antigens to prevent future attacks.
- The immune system includes primary lymphoid organs like the bone marrow and thymus, as well as secondary lymphoid organs like lymph nodes and spleen.
- There are two types of immunity: active and passive.
- Humans have two types of immunity: innate and adaptive.
- The adaptive immune system includes the cell-mediated immune response and the humoral immune response.
