Questions and Answers

What is a primary feature of innate immunity?

  • Targets specific antigens with high specificity.
  • Relies solely on the action of T lymphocytes.
  • Builds immunological memory for future exposure.
  • Involves the immediate response to pathogens. (correct)

Which of the following components is NOT associated with adaptive immunity?

  • Cytokines
  • T lymphocytes
  • Skin barriers (correct)
  • B lymphocytes

Which role do cytokines play in the immune system?

  • Neutralize foreign agents by binding to antigens.
  • Regulate and communicate between the innate and adaptive immune systems. (correct)
  • Directly kill bacterial cells.
  • Act as physical barriers against pathogens.

Flashcards

Innate Immunity

The body's primary defense system, responding rapidly to invaders like bacteria and viruses with non-specific mechanisms.

Adaptive Immunity

The immune system's 'smart' branch, targeting specific invaders and remembering them for faster future responses.

Physical barriers

The physical barriers that protect the body from invaders, like the skin and mucous membranes.

Antimicrobial chemicals

Chemicals that fight invaders, like lysozyme in tears, stomach acid, and complement proteins.
