What is the respiratory system?

The respiratory system is like your body’s breathing team.

It helps you take in oxygen and get rid of carbon dioxide. When you breathe in, air goes through your nose or mouth, down a tube called the windpipe, and into your lungs.

In the lungs, oxygen goes into your blood and carbon dioxide comes out when you breathe out.


The nose is like the entrance to the respiratory system. It has two holes called nostrils that let air in.

Inside the nose, there are tiny hairs called cilia and a gooey substance called mucus that help catch dirt and germs.

The nose also warms and moistens the air before it goes further into the body.


The mouth can also be used for breathing, but it’s not as good as the nose.

When we breathe through the mouth, the air doesn’t get filtered or warmed as well.

The mouth is mainly for eating and talking, but sometimes we have to use it to breathe if our nose is blocked or if we’re doing something like exercising.

The larynx is like the voice box in our throat. It’s responsible for making sounds when we talk or sing.

It has vocal cords inside that vibrate to produce different sounds. Sometimes, when we breathe in quickly or something irritates our throat, the larynx can make a sound called a cough.

The trachea is a tube that connects the larynx to the lungs. It’s also known as the windpipe.

The trachea is made of strong rings of cartilage that help keep it open. When we breathe, air travels through the trachea and goes into the lungs.

If something goes down the wrong way, like food or a drink, we might cough to try and get it out of the trachea.


The lungs are like two spongy balloons inside our chest. They are the main parts of the respiratory system where the magic happens.

When we breathe in, the air goes into the lungs and oxygen from the air enters our blood.

At the same time, carbon dioxide, which is a waste gas, comes out of the blood and goes into the lungs to be breathed out.

The lungs are super important for getting oxygen to all the parts of our body and keeping us alive!
