Detailed explanation-1: -This mucus builds up in the breathing passages of the lungs and in the pancreas. The buildup of mucus results in life-threatening lung infections and serious digestion problems. The disease may also affect the sweat glands and a man’s reproductive system. Many people carry a CF gene, but do not have symptoms.
Detailed explanation-2: -Bronchiectasis is a long-term condition where the airways of the lungs become abnormally widened, leading to a build-up of excess mucus that can make the lungs more vulnerable to infection. The most common symptoms of bronchiectasis include: a persistent cough that usually brings up phlegm (sputum) breathlessness.
Detailed explanation-3: -CF mucus is often described as more solid and having a “flake” form. In addition, it has a higher concentration of proteins called mucins. Mucins make up the main component of mucus and are responsible for the gel-consistency of mucus. Non-CF mucus is composed mainly by two types of mucins: MUC5AC and MC5B.
