Question

Which is an example of a substance or structure that performs a nonspecific immune response?

Answers

  1. The skin.
    • Rationale:

      The skin is an example of a structure that performs a nonspecific immune response within the body.

  2. The lungs.
    • Rationale:

      The lungs are not an example of structures that perform nonspecific immune responses within the body.

  3. The influenza vaccine.
    • Rationale:

      An influenza vaccine is an example of a substance that provides the body with artificial immunity; however, it is not a substance that performs a nonspecific immune response.

  4. The measles, mumps, and rubella vaccine.
    • Rationale:

      The measles, mumps, and rubella vaccine is an example of a substance that provides the body with artificial immunity; however, it is not a substance that performs a nonspecific immune response.

Overview

An immune response is defined as the reaction of the fluids and cells within the body to the presence of substances that are not recognized as normal body constituents.

Explanation

Learning Outcomes

The innate immune system consists of nonspecific immune responses. An example of a structure that performs nonspecific innate immune responses is the skin. The skin is the first line of defense against pathogenic infection and is a naturally occurring part of the body.

Test Taking Tip

Consider the definition of nonspecific immune response when determining the correct choice for this question.
