Immune System Flashcards
What is the primary function of the immune system?
The primary function of the immune system is to protect the body from harmful pathogens and foreign invaders.
True or False: The immune system can distinguish between self and non-self cells.
True. The immune system can distinguish between self and non-self cells to target and eliminate foreign invaders while protecting the body’s own cells.
What are the two main types of immunity?
The two main types of immunity are innate immunity and adaptive immunity.
Fill in the blank: The immune system’s first line of defense is the ________ barrier.
The immune system’s first line of defense is the physical barrier.
What are the primary cells involved in the adaptive immune response?
The primary cells involved in the adaptive immune response are T cells and B cells.
Which type of immunity provides immediate, non-specific protection against pathogens?
Innate immunity provides immediate, non-specific protection against pathogens.
What is the role of antibodies in the immune response?
Antibodies bind to specific antigens on pathogens, marking them for destruction by other immune cells.
True or False: Memory cells are a key component of the adaptive immune response.
True. Memory cells allow the immune system to mount a faster and more effective response upon re-exposure to a pathogen.
What is the process by which immune cells engulf and digest pathogens?
Phagocytosis is the process by which immune cells engulf and digest pathogens.
Which immune cells release histamine during an allergic reaction?
Mast cells release histamine during an allergic reaction.
What is the purpose of cytokines in the immune response?
Cytokines are signaling molecules that help regulate the immune response and communicate between immune cells.
True or False: Immunodeficiency disorders result in a weakened immune system.
True. Immunodeficiency disorders result in a weakened or compromised immune system, making individuals more susceptible to infections.
What is the term for the process of the immune system mistakenly attacking the body’s own cells?
Autoimmunity is the term for the process of the immune system mistakenly attacking the body’s own cells.
Which type of immunity is acquired through vaccination or exposure to pathogens?
Adaptive immunity is acquired through vaccination or exposure to pathogens.
What is the role of the thymus gland in the immune system?
The thymus gland is responsible for the maturation of T cells in the immune system.
Fill in the blank: The ________ response is the body’s initial, rapid response to infection.
The innate response is the body’s initial, rapid response to infection.
What are the two types of adaptive immunity?
The two types of adaptive immunity are humoral immunity (mediated by antibodies) and cell-mediated immunity (mediated by T cells).
True or False: Immunization is a method of artificially inducing immunity to a specific pathogen.
True. Immunization is a method of artificially inducing immunity to a specific pathogen through vaccination.
What are the primary organs of the immune system?
The primary organs of the immune system are the bone marrow, thymus, spleen, and lymph nodes.
Which type of immunity is present at birth and provides immediate protection against a wide range of pathogens?
Innate immunity is present at birth and provides immediate protection against a wide range of pathogens.
What is the role of dendritic cells in the immune response?
Dendritic cells are antigen-presenting cells that activate T cells and initiate the adaptive immune response.
True or False: Immunotherapy is a type of treatment that uses the body’s immune system to fight diseases like cancer.
True. Immunotherapy is a type of treatment that uses the body’s immune system to fight diseases like cancer by boosting or modifying the immune response.
What is the term for the ability of the immune system to recognize and remember specific pathogens?
Immunological memory is the term for the ability of the immune system to recognize and remember specific pathogens for a faster response upon re-exposure.
Which immune cells produce antibodies in response to pathogens?
B cells produce antibodies in response to pathogens.
