CYSTIC FIBROSIS

Part 1.

In this part of the activity you will visit the Cystic Fibrosis Foundation’s web site to learn about the causes and symptoms of cystic fibrosis.

Use your browser to go to http://www.cff.org/home/

Use the information provided in the “About cystic fibrosis” section to answer the following questions:

1. What are the signs and symptoms of cystic fibrosis?
Very Salty tasting Skwein
Persistent coughing, at all times with phlegm
Frequent lung infections
Wheezing or Shortness of Breath
Poor growth/ Weight gain in spite of a good appetite

2. How common is this disorder?
CF is the most common genetic (inherited) disease. Its affects about 30,000 children and adults in the u.s. and approximately 70,000 worldwideddd

3. How is cystic fibrosis diagnosed?
People with cystic fibrosis have between 2 and 5 times the normal amount of salt in their sweat. Doctors can use a sweat test to measure the amount of salt in a person’s sweat. In newborns, doctors can measure the amount of a protein call trypsinogen in the blood

4. How is cystic fibrosis inherited? Does everyone who has a mutant gene for the protein have cystic fibrosis?
Cystic fibrosis is a recessive disorder, which means that both parents must pass on the defective gene for any of their children to get the disease. If a child inherits only one copy of the faulty gene, he or she will be a carrier. Carrier don’t actually have the disease, but they can pass it on to their children

Part 2.

In this part of the activity you will read an article to learn more about cystic fibrosis.

Use your browser to go to:

http://resources.schoolscience.co.uk/MRC/3/page3.html

Use the information in this article to answer the following questions:

1. Explain the normal function of the protein that is defective in cystic fibrosis.
The normal function of the defective protein in CF is that the protein provides enough water and salt to the mucus, allowing it to flow and move smoothly out of the lungs and air passages

2. What happens to this protein in CF patients and what are the consequences for the health of these individuals?
Chromosome 7 is one of the 23 pairs of chromosomes that are part of each person’s genetic makeup. The CF gene causes the production of a protein that lacks an important amino acid.

Part 3.

In this part of the activity you will read about how cystic fibrosis is treated.

Use your browser to go to:

http://www.mayoclinic.com/health/cystic-fibrosis/DS00287

Use the information in the different sections of the article to answer the following questions:

1. Explain at least 3 treatments for the symptoms of cystic fibrosis.

Medicatation up to date.ion:
You can take mucus thinning drugs and antibiotics to keep the mucus moist. Also, you can take bronchodialators to relax the airways

Lung Transplant
When a lung isn’t able to function they need to replace it with a donor

Physical Therapy
Loosening the mucus. Feels better and slows process


2. Discuss at least 3 ways for parents to help their children who have cystic fibrosis.

Three Ways: Drink enough fluids, make sure they wash their hands and are clean, keep immuniz
