Immunity Questions and Correct Answers/
Latest Update / Already Graded
What is the main function of the immune and inflammatory systems?
Ans: To protect the body from illness and infection through a
coordinated response.
What is immunocompetence?
Ans: The ability of the immune system to mount an adequate
defense.
What is self-tolerance?
Ans: The immune system's ability to recognize and not attack
the body's own cells.
Why are immunocompromised patients at high risk for infection?

Ans: 1. Physical/Chemical Barriers, 2. Inflammatory Response,
3. Adaptive Immunity.
What are examples of physical and chemical barriers?
Ans: Skin, mucous membranes, and stomach acid.
What are characteristics of the inflammatory response?
Ans: Immediate and non-specific; involves neutrophils and
macrophages.
What is adaptive immunity?
Ans: A specific immune response involving T and B cells that
forms memory.
What are the stages of inflammation?
Ans: Vascular response, cellular exudate response, and tissue
repair/replacement.
What happens during the vascular response?
Ans: Vasodilation and increased permeability cause redness,
heat, and swelling.
