How Does Nasopharynx and Oropharynx Work?

The nasopharynx and oropharynx are parts of your throat that help you breathe and swallow.

Imagine your throat is like a hallway. The nasopharynx is the part near your nose, it's like the front entrance of the hallway. When you breathe in through your nose, air goes through this part first. It’s like walking into a room from the front door.

The oropharynx is the part behind your mouth, it's like the middle of the hallway. When you eat or drink, food and liquids go through here on their way to your stomach. It's also where sounds come from when you talk, kind of like a speaker in the middle of the room.

When you breathe in through your nose, air travels from the nasopharynx down to your lungs. When you eat, food goes from your mouth into the oropharynx, then down to your stomach.

Sometimes, when you’re sick or have allergies, this hallway gets a little crowded, that’s why it might feel harder to breathe or swallow. But most of the time, everything moves smoothly, just like people walking through a quiet hallway.
