Which body system is primarily involved in cystic fibrosis?

Cystic fibrosis is primarily a genetic disorder that affects multiple systems in the body, but it most significantly impacts the respiratory, digestive, and endocrine systems.

The respiratory system is involved because cystic fibrosis leads to the production of thick, sticky mucus that clogs the airways, resulting in breathing difficulties and frequent lung infections. The digestive system is affected since the thick mucus can also block the pancreatic ducts, hindering the proper digestion of food and absorption of nutrients, often leading to malnutrition. Additionally, the endocrine system is impacted because the malfunctioning of glands can affect various bodily functions, including insulin production, leading to diabetes in some individuals with cystic fibrosis.

This multi-system involvement is why the answer includes all three systems as being primarily involved in cystic fibrosis. Each system's role underscores the complex nature of this disorder, highlighting that it does not solely affect one part of the body but rather has widespread implications for overall health.
