Study Notes

  1. The immune system has innate and adaptive responses.
  2. Innate immunity provides initial danger signals that stimulate adaptive immune responses.
  3. Adaptive immunity intensifies the protective mechanisms of innate immunity.
  4. The immune system is systemic and does not react against the body's own tissues.
  5. Responses are regulated by feedback mechanisms to prevent inappropriate or pathological reactions.
  6. Innate immunity has an immediate response to repeated exposures, while adaptive immunity has a slower response.
  7. Innate immunity has limited specificity, while adaptive immunity recognizes a large number of antigens.
  8. Adaptive immunity has a memory component that allows for a faster and stronger response to a second exposure.
  9. Both innate and adaptive immunity have components of cellular and chemical barriers.
  10. Macrophages and neutrophils are important cells in the innate immune response.
