===Meaning===
'''Cystic Fibrosis''' is an [[Inherited Disorder|inherited disorder]] which causes the [[Goblet Cell|goblet cells]] to produce too much [[mucus]].

===About Cystic Fibrosis===
: The [[Goblet Cell|goblet cells]] which are found in the [[Breathing System|breathing system]] and [[Digestive System|digestive system]] produce too much [[mucus]] which can block small passages causing difficulty [[breathing]] and [[Absorb (Biology)|absorbing]] food.
: '''Cystic Fibrosis''' is caused by a [[Recessive Allele|recessive allele]] and can be passed from parent to [[offspring]].

| style="height:20px; width:200px; text-align:center;" |In this [[Punnett Square]] the [[Cystic Fibrosis]] [[Recessive Allele|recessive allele]] is represented with a lower case 'c' while the healthy variant of the [[allele]] is [[Dominant Allele|dominant]] and shown with a capital 'C'. This shows how two [[heterozygous]] parents who do not have symptoms of [[Cystic Fibrosis]] may carry the [[disease]] and pass it on to their [[offspring]]. This shows there is a 25% chance of a child [[Heredity|inheriting]] [[Cystic Fibrosis]].

===Symptoms of Cystic Fibrosis===
: Too much [[mucus]] building up in the [[lung]]s leading to [[breathing]] difficulty and persistent coughing. 
: [[Malnutrition]] as food cannot be properly [[Digestion|digested]] due to the build up of [[mucus]] in the [[Digestive System|digestive system]].
