Cystic fibrosis (CF) is one of the most common lung diseases in children and is a life-threatening disorder that causes, among other things, lung infections and breathing difficulties.

Breathing is the most important thing your body does. Without breathing, you simply cannot live. It’s something you do without even thinking about — unless you suffer from a lung condition that makes your breathing a difficult task. There are many facts about the respiratory system and the lungs that most people are unaware of.
