How does cystic fibrosis affect my alveoli and blood capillaries?

Cystic Fibrosis: Sodium channels (a natural "salt" in your body, doesn't get moved in and of the cells properly ND causes mucus to build p, become sticky, and not move well. This prevents oxygen from getting into the alveoli and carbon dioxide from moving out.

CF: Cystic Fibrosis (CF) is an inherited disease that causes thick, sticky mucus to form in the lungs, pancreas and other organs. In the lungs, this mucus blocks the airways-even getting down to the small alveoli, causing lung damage and making it hard to breathe. Recent studies show there may be some blood vessel dysfunction causing an impaired exercise tolerance as well. Hope this helps.
