Quiz Preview

  • 2. 

    Which cell type forms part of the innate immune system?

    • B-lymphocytes

    • Granulocytes; basophils, eosinophils, neutrophils

    • Plasma cell

    • T-lymphocytes

    Correct Answer
    A. Granulocytes; basophils, eosinophils, neutrophils
    Explanation
    Remember B & T lymphocytes form the backbone of the adaptive immune response

    Rate this question:

  • 3. 

    The adaptive immune sytem is not antigen specific so doesn’t improve with repeated exposure to the same infectious agent?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The adaptive immune system is antigen specific, so that after exposure to an infectious agent, ‘memory’ cells develop. On subsequent exposure to the same agent, the adaptive immune response then occurs quicker and is of greater amplitude

    Rate this question:

  • 4. 

    What is the name given to the secreted, soluble form of Immunoglobulin (Ig)?

    • B-cell receptors (BCR)

    • Antibody

    • T-cell receptors (TCR)

    • Epitopes

    Correct Answer
    A. Antibody
    Explanation
    BCR and TCR are very similar in structure to immunoglobulin, however are found on the surface of B & T cells respectively. They bind to a specific antigen.
    Epitope - this is the secific part of an antigen that is recognised by an antibody or antibody receptor.

    Rate this question:

  • 5. 

    The myeloid lineage is responsible for the majority of the innate immune response?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The myeloid lineage consists of those cell types that react first to the presence of a pathogen.
    Cells of the myeloid lineage include the granulocytes and agranulocytes.

    Rate this question:

  • 6. 

    The Adaptive immune system reacts first to the presence of a pathogen within the body.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    False, remember, the adaptive immune system takes much longer to be effective – at least 12 hours post infection; whereas the innate immune sytem can respond to a pathogen witin minutes of the initial infection

    Rate this question:

  • 7. 

    What are the main functions of the lymphatic system?

    • Maintaining the bodies fluid balance

    • Facilitating lipid absorption in the small intestine

    • Trapping and retaining infectious agents, presenting them to the cells of the Immune System

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The lymphatic system has multiple functions, including maintaining the body's fluid balance, facilitating lipid absorption in the small intestine, and trapping and retaining infectious agents, presenting them to the cells of the immune system.

    Rate this question:

  • 8. 

    Which of the following is referred to as a primary lymphoid organ?

    • Appendix

    • Bone Marrow

    • Kidney

    • Spleen

    Correct Answer
    A. Bone Marrow
    Explanation
    A primary lymphoid organ is one where lymphocytes are produced from immature progenitor cells. There are two such organs in the human body, the bone marrow and the Thymus.
    Secondary lymphoid organs are where mature lymphocytes reside and from where the adaptive immune response is initiated. Secondary lymphoid organs include the spleen, lymph nodes, and accessory lymphoid tissue, such as the tonsils, appendix, peyer’s patches, MALT & GALT.

    Rate this question:

  • 9. 

    Which term best describes the effect of a cytokine, which acts via the bloodstream on distant cells?

    • Autocrine

    • Endocrine

    • Paracrine

    • Tyranasorusrex

    Correct Answer
    A. Endocrine
    Explanation
    Autocrine cytokines act on the same cell that produce them
    Paracrine cytokines act cells adjacent to the one that produced them
    Tyranasorusrex is a type of dinosaur that was an apex pretty predator who would have probably enjoyed eating me and you for breakfast...good guess though

    Rate this question:

  • 10. 

    To which part of the immune system do Dendritic cells belong?

    • The adaptive immune system

    • The innate immune system

    • Both

    • None of the above

    Correct Answer
    A. Both
    Explanation
    The dendritic cells are the only cells of the immune system to bridge both the innate and adaptive immune system

    Rate this question:

  • 11. 

    To which part of the immune system does the complement system of proteins belong?

    • The adaptive immune Sytem

    • The innate immune system

    Correct Answer
    A. The adaptive immune Sytem
    Explanation
    The complement system of proteins belongs to the innate immune system. This system consists of a group of proteins that work together to enhance the immune response, including inflammation and the destruction of pathogens. The adaptive immune system, on the other hand, is responsible for the specific recognition and elimination of pathogens through the production of antibodies.
