Questions and Answers
  • 1. 

    Where are T and B cells produce?Which one do you like?

    • A.

      Heart 

    • B.

      Bone marrow

    • C.

      Thymus

    • D.

      Spleen

    Correct Answer
    C. Thymus
    Explanation
    T and B cells are produced in the bone marrow, not in the heart or spleen. However, the thymus is also involved in the production and maturation of T cells. Therefore, the correct answer is Thymus.

    What are the two types of white blood cells?

    • A.

      Phagocytes and pathogens

    • B.

      Phagocytes and lymphocytes

    • C.

      Lymphocytes and  pathogen

    • D.

      Pathogen and lymphocytes

    Correct Answer
    B. pHagocytes and lympHocytes
    Explanation
    Phagocytes and lymphocytes are the two types of white blood cells. Phagocytes are responsible for engulfing and destroying pathogens, while lymphocytes are involved in the immune response and produce antibodies to fight against infections. These two types of white blood cells work together to protect the body from harmful pathogens and maintain a healthy immune system.

  • 3. 

    What is the role  of the immune system?

    • A.

      To protect your body from drugs and medicine

    • B.

      To protect your body from air and water

    • C.

      To protect your body from pathogens

    • D.

      To protect your body from itself

    Correct Answer
    C. To protect your body from pathogens
    Explanation
    The immune system's role is to protect the body from pathogens, which are disease-causing microorganisms such as bacteria, viruses, and fungi. It does this by recognizing and attacking these foreign invaders, helping to prevent infections and keep the body healthy.

    Rate this question:

  • 4. 

    What are two parts of the innate immune system?

    • A.

      Barrier and Phagocytosis

    • B.

      T cells and B cells

    • C.

      Antibodies and lymphocytes

    • D.

      Antigen  and CFT

    Correct Answer
    A. Barrier and pHagocytosis
    Explanation
    The innate immune system is the body's first line of defense against pathogens. It includes physical and chemical barriers, such as the skin and mucous membranes, which prevent pathogens from entering the body. Phagocytosis is another component of the innate immune system, where specialized cells called phagocytes engulf and destroy pathogens. Therefore, the correct answer is "Barrier and Phagocytosis".

    Rate this question:

  • 5. 

    Which cells are responsible for making antibodies?

    • A.

      Killer T Cells

    • B.

      Helper T Cells

    • C.

      B cell

    • D.

      Macrophages

    Correct Answer
    C. B cell
    Explanation
    B cells are responsible for making antibodies. B cells are a type of white blood cell that play a crucial role in the immune response. When they encounter antigens, they differentiate into plasma cells, which produce and secrete antibodies. Antibodies are proteins that bind to specific antigens, marking them for destruction by other immune cells. This process is essential for the body's defense against pathogens and foreign substances. Killer T cells, helper T cells, and macrophages have different roles in the immune response but are not directly responsible for producing antibodies.

    Rate this question:

  • 6. 

    A protein produced by a B cell of the immune system that destroys a pathogen

    • A.

      B Cell

    • B.

      Antibody

    • C.

      T Cell

    • D.

      Vaccination

    Correct Answer
    B. Antibody
    Explanation
    An antibody is a protein produced by a B cell of the immune system that specifically targets and destroys pathogens. When a pathogen enters the body, B cells recognize it and produce antibodies that bind to the pathogen's surface, marking it for destruction by other immune cells. Antibodies play a crucial role in the immune response by neutralizing pathogens and preventing them from causing harm to the body.

    Rate this question:

  • 7. 

    Enzyme present in saliva and tears that kills certain kinds of bacteria

    • A.

      Lysozyme

    • B.

      Histamine

    • C.

      Cytokines

    • D.

      Basophile

    Correct Answer
    A. Lysozyme
    Explanation
    Lysozyme is an enzyme present in saliva and tears that has antibacterial properties. It works by breaking down the cell walls of certain bacteria, leading to their destruction. This enzyme is effective against a range of bacteria, including those that cause infections in the mouth and eyes. Therefore, lysozyme plays an important role in the defense against bacterial infections in these areas of the body.

    Rate this question:

  • 8. 

    A plasma cell secretes

    • A.

      Immunoglobulin

    • B.

      Antigen

    • C.

      MHC

    • D.

      Interferon

    Correct Answer
    A. Immunoglobulin
    Explanation
    A plasma cell is a type of white blood cell that plays a crucial role in the immune response by producing and secreting immunoglobulins, also known as antibodies. These antibodies are proteins that specifically recognize and bind to foreign substances, such as pathogens or toxins, in order to neutralize and eliminate them from the body. Therefore, the correct answer is Immunoglobulin.

  • 9. 

    Cell mediated immunity is carried out by………….. while humoral immunity is mainly carried out by………………..

    • A.

      Epitopes/Antigens

    • B.

      T cells/B cells

    • C.

      Antibodies/Antigens

    • D.

      B cells/T cells

    Correct Answer
    B. T cells/B cells
    Explanation
    Cell mediated immunity is carried out by T cells while humoral immunity is mainly carried out by B cells. T cells are a type of white blood cell that directly attack infected cells and coordinate the immune response. They recognize specific antigens on the surface of infected cells and destroy them. B cells, on the other hand, are responsible for producing antibodies, which are proteins that recognize and neutralize antigens in body fluids. This division of labor allows for a coordinated immune response, with T cells targeting infected cells directly and B cells producing antibodies to neutralize pathogens in the bloodstream.

    Rate this question:

  • 10. 

    Injection of weakened form of a pathogen or a similar but less dangerous pathogen, to produce immunity is called

    • A.

      Vaccine

    • B.

      Specific immunity

    • C.

      Memory cell

    • D.

      Fever

    Correct Answer
    A. Vaccine
    Explanation
    A vaccine is a substance that is injected into the body to stimulate the immune system and provide immunity against a specific pathogen or disease. It contains weakened or killed forms of the pathogen or similar but less dangerous pathogens. This exposure to the pathogen triggers the immune system to produce a specific immune response, including the production of memory cells that remember the pathogen and provide long-term immunity. Fever is not the correct answer as it is a symptom of an immune response, not the process of injecting a weakened pathogen. Specific immunity and memory cells are related to the immune response but do not directly refer to the process of vaccination.
