Cystic Fibrosis - GCSE Biology Definition

Cystic Fibrosis is a genetic disorder that mainly affects the lungs and digestive system. It is caused by a faulty gene, which leads to thick and sticky mucus build-up in the body. This mucus can block the airways, making it difficult to breathe and increasing the risk of lung infections. It can also block the tubes that carry digestive enzymes from the pancreas, making it hard for the body to digest food and absorb nutrients. People with Cystic Fibrosis often need daily treatments to help manage their symptoms and improve their quality of life. It is an inherited condition, meaning it is passed down from parents to their children through their genes.
