Cystic fibrosis is an genetic disorder that causes severe harm to the lungs, digestive system and different organs within the body.
Cystic fibrosis affects the cells that turn out mucous secretion, sweat and digestive juices. These secreted fluids are normally thin and slippery. But in human Cystic fibrosis with, a defective sequence causes the secretions to become sticky and thick.
Instead of acting as a stuff, the secretions plug up tubes, ducts and passageways, particularly within the lungs and exocrine gland.
