What is the primary function of the immune system?
To protect the body from pathogens and foreign substances.
True or False: Antibodies are produced by T cells.
False, antibodies are produced by B cells.
Fill in the blank: The first line of defense in the immune system includes __________.
physical barriers like skin and mucous membranes.
What are the two main types of immune responses?
Innate immunity and adaptive immunity.
Which cells are primarily responsible for cell-mediated immunity?
T cells.
Multiple Choice: Which of the following is NOT a type of white blood cell? A) Neutrophils B) Erythrocytes C) Lymphocytes D) Monocytes
B) Erythrocytes.
What is the role of phagocytes in the immune system?
To engulf and digest pathogens and debris.
True or False: Vaccines work by stimulating the adaptive immune response.
True.
Fill in the blank: __________ are proteins that help to identify and neutralize pathogens.
Antibodies.
What is the function of memory cells in the immune response?
To provide a faster and stronger response upon re-exposure to the same pathogen.
Multiple Choice: Which type of immunity is acquired through vaccination? A) Passive B) Innate C) Active D) Natural
C) Active.
What is the main difference between active and passive immunity?
Active immunity results when the body’s OWN immune system produces antibodies in response to pathogens/antigens, while passive immunity involves receiving pre-made antibodies from another source eg Abs from mother to fetus

True.
Fill in the blank: __________ are specialized cells that produce antibodies.

What are antigens?

Multiple Choice: Which of the following is a function of cytokines? A) Promote cell division B) Signal immune responses C) Both A and B D) None of the above
C) Both A and B.
What is the role of helper T cells?
To activate B cells and other T cells.
True or False: Autoimmune diseases occur when the immune system attacks the body’s own cells.
True.
Fill in the blank: __________ is the process by which immune cells recognize and destroy infected cells.
Cytotoxicity.
What does the term ‘immunological memory’ refer to?
The ability of the immune system to remember past infections.
Multiple Choice: Which type of immunity involves antibodies passed from mother to child? A) Active B) Passive C) Innate D) Adaptive
B) Passive.
What is the function of regulatory T cells?
To maintain immune tolerance and prevent autoimmunity.
True or False: Allergies are an example of an overactive immune response.
