Cystic fibrosis (CF ) is a chronic disease that affects the lungs and causes other complications that essentially limits the ability to breathe progressively. The defect of the CFTR gene causes CF, the gene responsible for making a protein that controls the activities of salt and water that goes in and out of our body cells. This results with a thick buildup of mucus within the lungs and other organs. The buildup causes the airways to be clog while also trapping bacteria which leads to infections. The mucus also prevents the enzymes needed to break down food and absorb nutrients. The disease eventually causes respiratory failure because of extensive lung damage.
