Phlegm is the mucus which we can cough up from the lungs. In the mouth it mixes with http://www.answers.com/topic/saliva (spit) to become sputum, which is then expectorated: phlegm plus saliva equals sputum, which is commonly studied by doctors to give signs of what is happening in the lungs.
In health the output of phlegm is too small to be measured accurately, but estimates give values of 15-50 ml/day, a minute amount. This is carried up to the larynx by the ‘ciliary escalator’, the wave-like movement of the hairs on the cells lining the trachea and bronchi. Once in the larynx, the phlegm is either coughed out, or more usually swallowed with, at the most, a throat-clearing ‘huff’. In disease, excessive production of mucus in the airways is characteristic of illnesses such as chronic bronchitis, usually diagnosed by the large production of phlegm; the mucus stimulates nerve receptors in the lining of the airways, which excite http://www.answers.com/topic/cough, and this leads to the removal of the phlegm. The commonest causes of phlegm production are airways infections, such as influenza, and cigarette http://www.answers.com/topic/smoking. Smokers' cough is due to the irritation of smoke stimulating mucus output from the glands in the trachea and bronchi. At night this mucus stays in the lungs, and when the smoker gets up in the morning the accumulated mucus is coughed up. The greatest output of phlegm is seen in a rare condition, bronchorrhoea, in which as much as two litres/day of sputum may be produced.

Can a bad cough cause your ribs to hurt?
If you cough enough to make your ribs sore, a doctor's appointment is necessary to determine the cause, as you may break your ribs if it continues. If your cough is productive = you cough up phlegm, then do not take cough suppressant medication and be sure not to swallow the phlegm. An expectorant will help. If you have a dry cough = no phlegm, then a cough suppressant (antitussive) will do you wonders. However, most OTC products are ineffective, so get a prescription or ask your pharmacist for something with codeine. Alternatively, dark chocolate 100g or over can be very effective.
