Quote by: Technosoul  The purpose of the lungs is just that, to filter out tar (whatever) so it cannot get into the rest of the body. However you are also talking about a poor diet problem. Science has shown that if you eat at least one cup of dark green veggies each day (check health webpages to find out which veggies are best) that this will clean out your lungs and counter what you said concerning cigarette smoking. |
How about you go and try to clean out your air filter with some soap and water, maybe you'll save money on car parts. Filters aren't designed to be cleaned out. They are designed to absorb as much crap as they can to separate the good stuff from the bad stuff. Your spleen, liver and kidneys are also filters in your body.
Your spleen can easily get infected, but that is not an essential part of the body and can be removed if need be. The other two, not so much. If you drink an enormous amount of liquor, your liver will become damaged. Theres no amount of green veggies in the world that will make your liver function again, and you will need a transplant or you will die. Similarly, if you drink some water with some nasty chemicals in it, your kidneys can get damaged, and you can get a transplant, or die. Transplants are essentially changing that old air filter.
Also, last I checked tonsils filter out all the bad shit that you breathe in, they're supposed to be the buffer between the lungs. The lungs are not the filter, they are the engine, and when you get a bunch of crap in your engine, it ceases to function correctly. The difference is that you can take the engine apart and clean it, the lung, not so much.
