  • 2. 

    The body can only be harmed by parasitic infection.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because the body can be harmed by various factors other than parasitic infection. These factors include bacterial or viral infections, physical injuries, exposure to harmful substances, autoimmune diseases, genetic disorders, and many more. Therefore, it is incorrect to say that the body can only be harmed by parasitic infection.

    Rate this question:

  • 3. 

    Any substance that provokes the response of the immune system because it is foreign or unfamiliar.

    • Lymphocyte

    • Parasite

    • Antigen

    • Tonsils

    Correct Answer
    A. Antigen
    Explanation
    An antigen is any substance that triggers an immune response in the body because it is recognized as foreign or unfamiliar. When antigens enter the body, they stimulate the production of antibodies by the immune system to neutralize or eliminate them. Antigens can be molecules from pathogens such as bacteria or viruses, as well as allergens or toxins. The immune system's ability to recognize and respond to antigens is crucial for defending the body against infections and diseases.

    Rate this question:

  • 4. 

    Phagocytes are the cells responsible for producing antibodies to battle antigens.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Phagocytes are actually responsible for engulfing and destroying foreign particles, such as bacteria and dead cells, through a process called phagocytosis. They do not produce antibodies. Antibodies are produced by a type of white blood cell called B cells, which are part of the immune system. Therefore, the statement that phagocytes are responsible for producing antibodies is false.

    Rate this question:

  • 5. 

    Skin is a part of the lymphatic system.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement is false because the skin is not a part of the lymphatic system. The lymphatic system is a network of vessels, nodes, and organs that helps to remove waste, toxins, and other unwanted materials from the body. The skin, on the other hand, is the largest organ of the integumentary system and serves as a protective barrier for the body. While the lymphatic system does play a role in maintaining the health of the skin, they are separate systems with different functions.

    Rate this question:

  • 6. 

    T-Cells can be classified as either ___________ or _______________ cells.

    Correct Answer
    Helper Killer
    Killer Helper
    helper, killer
    killer, helper
    Explanation
    T-Cells can be classified as either helper or killer cells. Helper T-cells assist in the immune response by activating other immune cells, while killer T-cells directly attack and destroy infected cells. Both classifications are valid and can be used interchangeably to describe the different functions of T-cells in the immune system.

    Rate this question:

  • 7. 

    Vaccination is a form of what type of immunity?

    • Innate

    • Passive natural

    • Active natural

    • Passive artificial

    • Active artificial

    Correct Answer
    A. Active artificial
    Explanation
    Vaccination is a form of active artificial immunity because it involves the administration of a vaccine to stimulate the immune system to produce an immune response. The vaccine contains weakened or inactivated pathogens or their components, which triggers the production of antibodies and memory cells. This creates a long-lasting immune response, providing protection against future infections by the same pathogen. Active artificial immunity is different from active natural immunity, which occurs when a person is exposed to a live pathogen and develops immunity through natural infection.

    Rate this question:

  • 8. 

    _______________ _____________ occurs when the immune system responds to only one problem.

    Correct Answer
    Specific Immunity
    Explanation
    Specific immunity occurs when the immune system responds to only one problem. It is a targeted response that is specific to a particular pathogen or antigen. This type of immunity involves the recognition and memory of specific antigens, allowing the immune system to mount a more efficient and effective response upon subsequent exposures. Specific immunity is mediated by specialized cells such as B cells and T cells, which produce antibodies and coordinate immune responses. This type of immunity is important for fighting off specific infections and providing long-term protection against specific pathogens.

    Rate this question:

  • 9. 

    ______________ occurs when the immune system is not able to perform to its' best ability.

    Correct Answer
    Immunosuppression
    Immunosupression
    Explanation
    Immunosuppression refers to a condition where the immune system is weakened or compromised, resulting in its inability to function at its optimal level. This can occur due to various factors such as certain medications, diseases like HIV/AIDS, or medical treatments like chemotherapy. Immunosuppression can leave an individual vulnerable to infections and diseases as the body's ability to fight off pathogens is diminished. The term "Immunosupression" is likely a typographical error as the correct spelling is "Immunosuppression."
