During breathing, air is normally brought in through the nose where it is warmed, filtered, and humidified. It then passes through the throat and into the windpipe, called the trachea (TRAY-kee-a). The trachea divides into two large tubes called the right bronchus (BRONG-kus) and left bronchus. These then split up into much smaller tubes, which in turn branch into thousands of very small airways called bronchioles (BRONG-kee-olz). It is the large and small bronchi that are generally affected in asthma.
