why do we get bugger in our noses?

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!!

Probably the same reason pulling hair from your head does. Even more so I guess as inside the nose is more sensitive that your head. If you plucked pubic that would hurt for the exact same reason.     :-)  Ouch makes my eyes water thinking about it.

NOT EVERY BODY PICKS IN THEIR NOSE. THEY SAY IT'S NASTY OR DISCUSSING, but every once in a while somebody catches them digging in. It's human nature to do so. I've caught plenty of people and i have done so myself especially when it to deep to even blow it out!!

Of course, its a perfectly natural situation. Something that irritates the nostrils' delicate lining makes the nerve endings not only say that 'hey there's an itch here too!' but the sneeze reflex also responds to the irritant.

Why do our noses run?\nOur cough reflex is not the only way we have to protect our airways. Most of the time we breathe through our noses. There are several folds and ridges at the back of the nose, on the way to the throat and windpipe, which are covered with mucous membranes. These membranes secrete mucus, a thin but slightly sticky liquid. As the air we breathe passes over these folds and ridges, it is humidified by evaporating water from the membranes and mucus, and many of the dust particles present in the inhaled air stick to the mucus so they cannot continue to the lungs. (Mucous membranes also line the windpipe and airways and help to trap smaller dust particles, and there are microscopic hairs, known as "cilia", on the surface of the lung's mucous membranes that continuously "sweep" the dirty mucus up through the airways and toward the windpipe where you can cough it all the way out.) \n\nSometimes, when our noses and lungs are irritated by something in the air, our mucous membranes will produce more mucus to help pick up and clean out the irritants. This can also happen when we breathe in something that we are allergic to: the allergic reaction of the mucus membranes to the offending material makes the membranes produce a lot more mucus, and a lot of extra water enters that mucus because of the allergic effect on the membranes. Unfortunately, the excess mucus and water makes you very uncomfortable and doesn't do any better as far as self-cleaning goes. \n\nViruses can also attack the mucus membranes and cause extra watering and extra mucus production. This, in fact, is how the common cold occurs. The virus is spread from person to person through droplets in the air or on hands: remember that there's a lot of extra liquid around with all the irritation, and a lot of that is sprayed into the air every time you cough or sneeze. Other people who breathe those droplets may be infected also, since the droplets will be caught on their mucus membranes. Once you've been infected by a particular cold virus you'll be immune to it forever, but there are hundreds of cold viruses around for you to catch, and there'll almost always be a few around that you haven't had yet. Since, as with the vast majority of viruses, there are no medicines we can use to kill cold viruses, when we get a cold we have to wait it out, possibly with medicines to relieve some of the misery.

The sinus inside the nose builds up from the lack of warm oxygen. Thus, when you are in a cold area, you feel the clogging of your nose and eventually you will have snot.\n\nIf your nose is runny,\nAnd you think its funny,\nWell, it's snot.\n\n- ICE, Gaylord Palms FL

To make funny faces, wierd noises, and get gooey.  Pretty much to keep us from getting too uptight about life.

S'not funny, is it? It's why most people get nose bleeds when they have colds, cos they bust blood vessels trying to get at stuff which isn't there.

You sneeze because you have something in your nose and your body is trying to get it out.  You don't get it out the first time, or your nose is still irritated.

"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♥

There are two common types of disease. Bacterial and viral. People become sick by either being exposed to a large amount of a particular germ (bacterial or viral) or being exposed to one their immune system doesn't yet know how to fend off.\n\nWhy do people often get a runny nose and a cough/sneeze? When your body is fighting a disease, it builds up excess waste in the lungs (especially if it's a respiratory disease) the body removes this waste bay causing you either to sneeze or cough or making your nose run.\n\nWhy do people get a fever? A common way for your body to fight an infection is to overheat your body so that the bacteria or virus will no longer be able to survive.

1. It creates the boogers, and we all know how much fun we have when we pick our nose.\n2. It helps the economy by making people buy tissues (when the nose starts running). \n\nWhy don't you try to be a real student?

Our skin has a defense system that makes us aware of annoying things that touch our body. Sometimes that annoying thing is just a fly. But sometimes we come into contact with something like poison ivy that causes a reaction in our skin. Poison ivy or bug bites cause an allergic response that keeps our skin itchy for a while.

You mean we don't? No wonder I've been getting funny looks and pops on the nose.

That is called the "Filtrum"  This may sound a bit disgusting, but it is there to prevent matter from your nose, from entering in to your mouth.  It deflects the "matter" off to the sides.

Wait, babies are coming out of your nose? That sucks. Or do you mean snot? If that's the case, just blow your nose and take an allergy pill.

How come your feet smell, but your nose runs???
