What is Asthma?

Asthma is a disease of the respiratory system. Your respiratory system is made up of:

  • your nose and mouth
  • your windpipe (also called your trachea, pronounced tray-key-uh)
  • your lungs
  • a bunch of air tubes (or airways) that connect your nose and mouth with your lungs
    (these are called bronchi and bronchioles, pronounced bron-kye and bron-key-oles).
