Glands found in your nose, throat, and several other parts of your body produce up to two quarts of mucus a day. Although people tend to think of mucus as an annoyance, it serves several important functions, including humidifying and cleansing air before it reaches your lungs. It also plays an important role in clearing away foreign invaders like bacteria and viruses before they can get into your body and cause an infection.
