What gives mucus color when you're sick?

It's a good thing I'm used to you.

In the airways, mucus are synthesized and secreted by goblet cells and from submucosal glands along the respiratory tract. Mucous cells secrete mucins, while serous cells secrete most of the other constituents of mucous, including IgA, antiproteases, proteases and fluid. Secretion of mucus components from serous and mucous cells is induced by a variety of stimuli including acetylcholine, arachadonic acid, prostaglandins, histamine and neutrophil elastase. Illness affects these factors, causing them to change the mucus characteristics. Gets?

hi Spanky! I recall my pediatrician telling me back in third grade that the darker the color of your sipon is, the better. This means that you're closer on your way to recovery. Is this true, Doc I? I seem to think so. When my sipon is purely transparent, it takes longer to heal than when it's off-white. Am I bordering on the disgusting as well?

Heeyipes! Really?!? Oh well... almost all the time, mine is colorless so I guess I'm safe... you're kidding about mucus being bluish, right??!?? How can anyone have blue sipon!?!?
