CysticFibrosis
Cystic Fibrosis is an inherited chronic disease that affects the lungs and digestive system.
1) What are the signs and symptoms of cystic fibrosis?
A: Signs- The body produce unusual sticky, thick mucus.
Some symptoms are very salty tasting skin, wheezing, poor growth, frequent lung infections, etc.
2) How common is this disorder?
A: Around 1,000 new cases are diagnosed each year.
3) How is cystic fibrosis diagnosed?
A: Sweat Test, Newborn Screening, and Genetic Carrier Testing.
4) How is cystic fibrosis inherited? Does everyone who has a mutant gene for the protein have cystic fibrosis?
A: It is inherited when two mutated CFTR genes one from each parent.
No, they could carrie it, or not even be affected and some also could be affected.
Part 2
1) Explain the normal function of the protein that is defective in cystic fibrosis?
A) The basic defect in CF arises particularly in the epithelial cells living the airways of the lung.
2) What happens to this protein in CF patients and what are the consequences for the health of these individuals.
A) The vital chloride channel is blocked, with no ionic gradient there is no need for water town moves towards the surface and the mucus dries out.
Part 3
1) Explain at least 3 treatments for the symptoms of cystic fibrosis.

Part 3
1) Explain at least 3 treatments for the symptoms of cystic fibrosis.
A)-Lung transplant-Go into surgery and replace a lung with a healthy lung.
-Liver transplant-Go into surgery and replace the diseased liver and replace it with a healthy liver.
-Gene therapy-Altering the genes inside your bodys cells to stop the disease.

2) Discuss at least 3 ways for parents to help their children who have cystic fibrosis.
A) -Drink lots of fluid-Fluid intake can help thin the mucus in your lungs.
-Exercise-Helps loosen mucus in your airways and strengthens your heart and lungs.
-Elliminate smoke-Don't smoke or allow others to smoke around you.
