The cause of excess mucus is as a result of the infection.\nThe virus irritates the membranes of the sinus and or lung, intitiating excess fluid to be created to remove the virus from the airways.

Empyema is a condition in which pus and fluid from infected tissue collects in a body cavity. The name comes from the Greek word empyein meaning pus-producing (suppurate).

Our respiratory is coating in mucous, and also lined with ciliated cells ( they kinda have fingers) that push all the mucous up toward our nose and mouth.  When the mucous gets there then it is either expelled or it dries, making boogers!!

Coughs are usually nature's way of clearing secretions from the nose, throat or lungs. Dry coughs are caused usually by a virus and can be helped by increasing your fluid intake, inhaling steam from a kettle and hot drinks. A prolonged cough for more than two weeks is reason to see the doctor.

I would venture to guess that it is because your tubes in your lungs get smaller when you are cold.  This forces whatever mucus in your lungs be more in the way of your breathing, so you have to cough.

legionnaires disease is something you get from the water in one of those refrigerated water coolers, or from moldy air conditioning. don't get too paranoid, though, i think it's pretty rare.

Most people who come from asia live in a very polluted environment. Maybe its the smell of factories and dead fish mixed with his fart that you smell?\n\nThe fart of the white man is usually from burgers and beans and meaty objects. Some people get their farts from vegatables. Our food is fresh, maybe asian people food is polluted?

LOL. you are very curious child. technically no. the air from sneezing comes from your lungs...its a reflex to get an irritant out of your system. while farting is caused by some trapped gas within your digestive system and the stomach is way too far to be the reason for farting...the gas is somewhere in your intestines [large intestine]. and besides, sections of your intestines are segmented by circular and longitudinal muscles so it can't be the stomach. so no. it doesn't form a vacuum. interesting question though.

"Boogers" are just phlegm. Your nose creates mucus (the "boogers") to gather all the dust and crap in your nose, and then it dries up and falls out.\n\nIt's sort of like your own personal maintenance system. \n\n♥

It occurs when pressure is put on the bladder.  The pressure can be from lifting something too heavy, repeatedly standing for too long, coughing, sneezing and laughing.  And if you're a woman, pregnancy and childbirth can cause it.

it's called a tonsolith, usually from food or debris that gets stuck in one of the crypts "pockets" in your tonsils.  The smell is from the bacteria breaking down the debris.
