Copied and edited from someone else's answer on a similar question (they're not registered on WikiAnswers or I'd reference them): They form because the water from their sweat evaporates and then the salt can't go with it! You might like to check the other questions regarding salt and cystic fibrosis as I don't think the above answer quite covers your question.
Cystic fibrosis
In cystic fibrosis, mutations in the CFTR gene prevent chloride ions from exiting cells properly. This leads to a buildup of chloride ions outside certain cells, causing a thick mucus to form in the airways and other organs.
I am going to presume that you mean a MediMist Nebulizer. This is a machine used to administer medication to people in the form of a mist inhaled into the lungs. It is commonly used in treating cystic fibrosis, asthma and other respiratory diseases.http://en.wikipedia.org/wiki/Nebulizer
Yes. Salts can form crystals (salt crystals).
Patients with ABPA sometimes cough up large amounts of blood, a condition that is called hemoptysis. They may also develop a serious long-term form of bronchiectasis.ABPA sometimes occurs as a complication of cystic fibrosis.
Hemochromatosis type 1 (or simply Haemochromatosis, or HH) is a hereditary disease characterized by excessive absorption of dietary iron resulting in a pathological increase in total body iron stores. Humans, like most animals, have no means to excrete excess iron. Excess iron accumulates in tissues and organs disrupting their normal function. The most susceptible organs include the liver, adrenal glands, the heart and the pancreas; patients can present with cirrhosis, adrenal insufficiency, heart failure or diabetes. The hereditary form of the disease is most common among those of Northern European ancestry, in particular those of Irish descent, and is currently the most common in the US.
Down syndrome is a polyploidy (three chromosome 21s)and is considered to be a somatic disorder. The other three are genetic because they are present in the form of a defective allele on achromosome.
a saturated solution will form crystals
When magma coos slowly, it allows large crystals to form. The process of evaporation helps to form crystals.
Gatorade will form crystals faster because it contains electrolytes, which are a form of salt. Salts are crystals, thus your answer. Pure water will not form crystals at all unless it reacts with another substance.
1. Cystic fibrosis is caused by recessive inheritance as is sickle cell disease, Tay Sachs, Phenylketonuria, Thalassemia, and Galactosemia. (i got that ot of the book) Cystic Fibrosis is caused by a genetic mutation.
Most minerals form crystals.
