Final answer:
Cystic fibrosis is an inherited disorder that affects the chloride ion channel, leading to lung congestion and infections.
Step-by-step explanation:
Cystic fibrosis is an inherited disorder that affects the chloride ion channel. It is caused by a mutation in the CFTR gene, which leads to the production of a faulty protein that is responsible for transporting chloride ions in and out of cells.
The impaired salt transfer results in abnormally thick and sticky mucus, which can lead to lung congestion and recurrent infections.
