Question

Quizplus · Accepted Answer

Cystic fibrosis is a genetic disorder that affects the secretion of mucus in the body, resulting in the production of thick, sticky mucus that can obstruct the airways, pancreas, sweat ducts, and vas deferens. This leads to respiratory problems, digestive issues, and infertility in males. Options A, B, and D do not match the description of cystic fibrosis. Option A describes asthma, Option B describes acute respiratory distress syndrome (ARDS), and Option D describes respiratory distress syndrome in neonates.
