Ready to learn way more about your nose than you ever thought you would know? Then let's get started.
1. Sinuses are a system of hollow air pockets that connect to the nose. (And they can be painful when there's an infection.) The sinuses are lined with a mucus-producing membrane that helps trap dust and other particles you breathe in, and they also decrease the weight of your skull so you have a lighter load to support.
2. Mucus membranes line the nasal cavity, secreting mucus that traps particles, bacteria, and viruses before they can reach the respiratory system. If the nose is aggravated (say, by cigarette smoke, allergies, or viruses), the membrane can become inflamed and swollen, and you may feel stuffed up.
3. Three turbinates are small, shelflike structures made of bone and soft tissue — direct inhaled air while also acting as your nose's central humidifier. They add moisture and warmth to the air as it flows by to keep the lungs and bronchial tubes from getting irritated.
4. Nares, also known as nostrils, lead to the nasal passage. Just inside the nares are hairs that help filter out larger airborne debris.
1 liter: About how much mucus your nose produces daily (seriously), most of which you end up swallowing.
100 mph: The speed at which particles and irritants shoot out of the nose when you sneeze.
19,000 liters: Approximately how much air passes through your nose each day en route to your lungs.
