Cystic Fibrosis is an inherited disease that affect tissues that produce mucus secretions, including the tissue that line the airway in the lungs, the digestive system, the ducts of the pancreas, and the ducts of the liver. It is the most common inherited disease leading to a shorten life span among whites. Cystic fibrosis involves changes in the chemical properties of mucus, causing "certain glands to produce an abnormally thick, sticky mucus that clogs the lungs and leads to life-threatening lung infections."(Wilhelm) "All these changes make breathing increasingly difficult and reduce the lungs' ability to transfer oxygen n to the blood."(Beers) These thick secretions also obstruct the pancreas, which prevents digestive enzymes from reaching the intestines not allowing the break down and absorption of food leading to in many cases nutritional deficiencies. In the liver, the thick secretion blocks the bile duct causing inflammation and eventually...
