What characteristic of Cystic Fibrosis leads to respiratory complications?

Cystic Fibrosis is primarily caused by a mutation in the CFTR gene, which leads to the production of thick, sticky mucus in various organs, particularly the lungs. This thick mucus impairs the normal functioning of the respiratory system in several ways.

Firstly, the excess mucus creates an environment that is conducive to the growth of bacteria and other pathogens, making individuals with Cystic Fibrosis more susceptible to respiratory infections. These infections can lead to chronic inflammation and damage to lung tissue, ultimately resulting in respiratory complications.

Secondly, the thick mucus obstructs the airways, making it difficult for individuals to breathe properly and clear out secretions. This can lead to diminished airflow and reduced oxygen exchange in the lungs, further complicating respiratory health.

Overall, it is the presence of this thick, sticky mucus that disrupts normal respiratory function and leads to the complications associated with Cystic Fibrosis.
