Explanation: 

Detailed explanation-1: -Simply put, cystic fibrosis is a gene defect. A defect to this gene changes how a salt moves in and out of cells, resulting in thick, sticky mucus in the respiratory, digestive and reproductive systems.

Detailed explanation-2: -Definition. Cystic fibrosis is a disease that causes thick, sticky mucus to build up in the lungs, digestive tract, and other areas of the body. It is one of the most common chronic lung diseases in children and young adults. It is a life-threatening disorder.

Detailed explanation-3: -In people with cystic fibrosis, mucus is dehydrated, becoming so thick and sticky that the cilia are unable to propel mucus out of the lungs. As a result, the mucus clogs the airways. The largest airway is the trachea between the throat and the lungs.

Detailed explanation-4: -Cystic fibrosis is an inherited condition in which the lungs and digestive system can become clogged with thick, sticky mucus. It can cause problems with breathing and digestion from a young age. Over many years, the lungs become increasingly damaged and may eventually stop working properly.

Detailed explanation-5: -CF causes thick mucus that clogs certain organs, such as the lungs, pancreas, and intestines. This may cause malnutrition, poor growth, frequent respiratory infections, breathing problems, and chronic lung disease. There is no cure for CF.
