Breathing difficulties caused by cystic fibrosis primarily impact which system in the body?

Breathing difficulties caused by cystic fibrosis primarily impact the respiratory system. Cystic fibrosis is a genetic disorder that affects the cells that produce mucus, sweat, and digestive fluids. In individuals with this condition, thick and sticky mucus builds up in various organs, especially the lungs. This accumulation obstructs the airways, leading to severe respiratory issues, including chronic infections, inflammation, and difficulty breathing.

The primary function of the respiratory system is to facilitate the exchange of gases (oxygen and carbon dioxide) between the body and the environment. Since cystic fibrosis disrupts this process through the buildup of mucus in the airways, it directly affects the respiratory system’s ability to function correctly, resulting in significant breathing difficulties.
