AllergiesSee Lesson Ideas for this topicThe immune system is responsible for protecting the body against potentially harmful, foreign substances. Antibodies circulate through the bloodstream in order to fight off these substances. In allergy sufferers, however, the immune system overreacts, releasing antibodies to attack harmless substances. This triggers the release of histamine, which causes symptoms such as sneezing, watery eyes, and temporary rashes. Achoo! |
