I'm not a doctor or have any professional or eductional teachings of cancer. But I found out last year from the D.A.R.E. program at my son's school is that each time you smoke a cigarette, the chemicals that are in the smoke are drawn into your lungs and they adhere to the vili in the bronchial tubes. This tar substance lines the tubes and weighs heavy on the vili, hairlike tissue that is used to clean the air that enters the lung. The tar substance ends up lining the tubes and narrows them, like cholestrol in arteries, making the tubes smaller and smaller. This makes it harder for the lungs to inhale air and the lungs stop absorbing the oxygen they need to properly oxygenate the blood cells. Your lungs have to work harder to inhale oxygen and your blood cells carry less oxygen to all  the other organs. Also the tar substance will eventually close of some tubes all together and will less oxygen in the lung itself, lung tissue cells die off and are never replaced. Parts of your lung die, parts can't work properly and other parts form cancer cells.\n\nThis is part of the information that my son brought home from D.A.R.E. 2 years ago and I stopped smoking after reading this. I don't know how my damage my lungs are in or if I will end up with cancer some day from the 13 years of smoking I did do, but I do notice that I breath better, I don't cough or wease anymore and I have more energy. My son saved me.

If the air is dry or cold, then when you inhale, the moisture gets taken from your lungs into the air (since hot air can hold more moisture - when the air heats in your lungs it needs moisture and takes it).  When you breathe a lot more, like when you exercise, the lungs dry out more than normal.  This drying of the lungs is normally felt as a painful burn, and it's why when people run in cold weather they normally try to breathe through their noses.  The passage through the sinuses is longer, and gives the air more time to heat up and absorb moisture on the way down to the lungs instead of in the lungs themselves.  Try to pay attention and always breathe in through your nose while exercising.  See if this helps.  If it does, and you work out at home, then you could try to get a humidifier.

Lungs. Same as humans and most land mammals.

Air molecule???\nThe air we breath, Oxygen Nitrogen (not nitrate, just oxygen and nitrogen), goes in through your nose down to your lungs. Your red blood cells have tiny holes on them, and they "collect' the oxygen from your lungs, back to the heart, and gets pumped everywhere through your body. Your body takes the oxygen, have a bunch of reactions with them, and sends out the "waste" (carbon dioxide, etc), which goes back to your ticker, pumps it up to your lungs, and is breathed out. \n\nPlease, don't just use that as your research paper. It is much more detailed. :P

Your lungs inflate because your chest expands (intercostal muscles flexing) and the diaphram flexes. This creates negative pressure inside the pleural cavity and causes the lungs to inflate (the actions of the chest wall and diaphragm essentially creates a vacuum and air tries to enter through the nasal or oral cavities, to reduce the vacuum)

you use a nebulizer to treat lungs expansion

well, your lungs because when you walk,runplay basketball, play tennis or even golf. smoking effects your lungs and slows you down in any physical activity

There are hairs in the nose that filter out such particles. When breathed in through the mouth, there are other things as well in the windpipe, etc that prevent many contaminants from reaching the lungs.

Occupational exposure to any fumes and/or chemicals can create inflammatory responses within your lung tissue. When this inflammation occurs on a daily basis over a several year period, your lung tissue, specifically the parenchyma will become damaged similiar to that of a chronic smoker. The parenchyma is the distal portion of your lungs that partake in gas exchange (Co2 and 02), when this layer of blood vessels and tissue become destroyed, there is no way to repair the damage. Just think of a coal miner's lung

Our lungs can not hold water, it is to hevy and your lungs can burst. I am a doctor so I know these kinds of questions.\n\nThank you!

core? of your chest?\nthat would be your heart/lungs area

muscular system helps you move.....with out that you couldnt move anywhere......respiratory helps you breath.......circulatory helps the blood move through the body and other fluids get where they are going

That says that you had a good workout.  You may expand your lung capacity by taking long deep breaths and hold as you perform light exercises....

Generally white saliva or mucous is a normal way for the lungs to keep themselves clean. If it is thick you may be dehydrated. The easiest way to make mucous thinner is to drink water. Water helps thin out the mucous and make it easier for the body to absorb. If you have any color like yellow, green, brown, you might have some kind of infection.
