Cystic fibrosis

[Renato]

Cystic Fibrosis is a disorder of the cell membranes, causing them to produce too much [mucus], and so this tends to [block up] the lungs, making it difficult for the person to breathe. People with this condition often have to have breathing exercises to shift excess mucus. It can be inherited if two recessive [genes] are combined.

[Raeanne Dimick]
