Your nose has many important jobs, and is always busy.

Smelling

    Smelling helps you gather information about the world around you. A good scent (气体),like flowers, brings you pleasure. A bad scent, like smoke or sour milk, warns you of danger. Most things around you release scent particles (微粒) into the air. These invisible chemicals enter the nose when you breathe. Nerves in the nose send information to the brain to identify a smell. You are able to recognize thousands of smells.

Breathing

    Most of the air you breathe enters through your nose. The nose uses hair and mucus (粘液) to clean dust and germs (细菌) out of the air. The air that enters your nose contains oxygen. Your body uses oxygen to unlock the energy in the food you eat.  Even when you sleep, your body needs energy to keep your heart beating and your brain working.

Tasting

    Your nose helps you enjoy food. Flavor is a mixture of taste and smell. The smell of the food helps you identify what you are eating. The sense of smell contributes more to (贡献) food flavor than the sense of taste .When you are sick and have a stuffy nose, your food doesn't taste as good because without smell, food loses most of its flavor.

Smell memory

    Smells can bring back memories. Your brain uses a process to create a picture in your mind from the odors(气味)you smell. Smells can affect your feelings because the part of the brain that helps you identify smells is close to the area that affects your emotions, mood and memory. More smell memories are collected as you get older.

    Your nose has many important jobs, and is more than just a smeller!
