Question

Quizplus · Accepted Answer

Cystic fibrosis is a genetic disorder that leads to the production of thick, sticky mucus in the lungs, digestive system, and other organs. In the lungs, this mucus can obstruct airways and lead to difficulty breathing. The mucus elevator, which normally transports mucus out of the lungs, is overwhelmed by the excess mucus production, leading to periodic episodes of severe breathing problems. Options A, B, D, and E are not typically associated with cystic fibrosis.
