Immune System

  • step 1

    person eats an allergen or substance that causes an allergic reaction for the first time
  • step 2

    after the person eats the allergen, the body will then create an antibody/protien that finds other harmful substances
  • step 3

    the antibody attaches itselft to cells found in tissues throughout the body so it can prepare the body for if/when that allergen enters the body again
  • step 4

    after entering again, it binds to the antibodies and sends out signals to release large amounds of histamine
  • step 5

    the histamine then causes irritation and swelling in differnet parts of the body
  • step 6

    step 6
