Well, if you inhale it hard enough--past your sinuses--yes.
After entering your nose and mouth, air travels down your windpipe (trachea) and into your lungs.
the air has to go through your nose and the hair in your nose cleans the dust and every thing thatsshouldn't get into your nose and your system!!
Go and see your piercer to have them help you figure out what it is and how to treat it.
As you breathe through your nose, it will go through the windpipe and into your lungs. It will go through tiny holes in the lungs. The wastes will get out from the tiny holes into your windpipe and you breathe them out.
None. Go to your doctors.
Well first you suck off the coating. Then you snort it. Why would it enter your lungs? Your not inhaling it, you snorting it up your nose. If you smoked it, then it would go into your lungs.
Go see a vet, the kitten probably has pneumonia or bronchiectasis.
When you breath, your lungs can go up and out a little, but mostly, your lungs go down. The breathing device is the diaphragm, a sheet of muscles going across your chest inside front to back. As the diaphragm 'bends' itself down, the lungs have to move with it and get bigger. When the lungs get bigger, they have no choice but to suck in more air through the mouth or nose. When the diaphragm 'bends' or moves upward, air is pushed out of the lungs.
Sometimes, when people age they have poor hearts. The heart serves as a pump for two purposes: It pumps blood to the body, and it pumps blood to the lungs. Blood from the lungs goes to the heart to go to the body, and vice-versa. When the heart starts to weaken, and not pumping as strongly, the lungs can get backed up with fluid.
The mouth and the nose are connected at the pharynx. The reason food doesn't regularly go down into the lungs is the trachea, which isn't present for the nose, leaving it open for fluids to go through should other factors allow it to, like posture.
After entering the nose or mouth, oxygen travels down the windpipe (trachea) and then into the lungs. In the lungs, oxygen is exchanged for carbon dioxide in the alveoli, small air sacs where oxygen is taken up by red blood cells and transported to the rest of the body.
The germs in the air go through the hair in your nose and get caught in it, when they go through your mouth the bacteria is heading into your lungs and drys out your mouth if you sleep breathing through your mouth.
