  • Allergy – a disorder in which the immune system is overly sensitive to a foreign substance, something not normally found in the body.

  • Allergen – the substance that causes the allergy.

How it happens
How it Happens

  • The allergen gets into the body, and antibodies are produced.

  • The body then releases a chemical called histamine, which is responsible for sneezing, watery eyes, rash… ect.

  • The histamine causes the immune system to freak out about the allergen causing a much more violent reaction.


  • Asthma – respiratory disorder in which the passages narrow significantly.

    • Causes wheezing and shortness of breath

    • Attacks can also be triggered by stress and exercise.

    • Asthma attacks can get so bad that emergency medical help may be needed.
