The two bronchi are rigid tubes running between the trachea (the wind pipe) and the lungs, allowing air containing oxygen into the lungs, and ridding the body of carbon dioxide. In healthy individuals, a fine layer of watery mucus is secreted onto the surface of the bronchi to prevent infection and allow a smoother passage of air. Sometimes this system breaks down; for example, in those with cystic fibrosis, the body is unable to regulate the thickness and consistency of this mucus which often leads to bacterial infection, a slow degradation of this tissue, and great discomfort.
