Questions and Answers

What is the main difference between innate immunity and adaptive immunity?

  • Innate immunity is specific to a particular pathogen, while adaptive immunity is not.

  • Innate immunity is hereditary, while adaptive immunity is not.
  • Innate immunity is obtained through artificial means, while adaptive immunity is naturally acquired.
  • How is naturally acquired adaptive immunity most commonly obtained?

  • By receiving immune serum containing antibodies

  • Through receiving an antigen by injection
  • By antibodies transferred to fetus across placenta
  • What activates lymphocytes of the immune system in the case of natural acquisition of adaptive immunity?

  • Lymphocytes are activated by the antibodies released
