Lungs

My work on the Lungs

1. Your lungs take oxygen from the air you breathe in, for your body.

2. The oxygen in the air is passed from the tiny tubes in your lungs called bronchioles into your blood ad is shipped around your body.

3. Your body uses oxygen (02) and changes it into Carbon Dioxide (C02).

4. Your lungs also act as a full-time cleaner getting rid of the Carbon Dioxide from your body, which is exhaled out of your nose or mouth.

Your lungs have no muscles.

Your body uses rib cage muscle called diaphragm, to pull air into your lungs.

All living things need oxygen to survive.

You’ve got over 600 million tiny air sacs in your lungs called alveoli and if you laid them all out in front of you they would cover a tennis court.

If you smoke cigarettes, the tar and chemicals from smoke clog up the tiny bronchioles and alveoli so it is really hard for your body to absorb oxygen.   Air that we breathe is made up of thousands of gases. 78% is nitrogen gas 21% oxygen, and the other 1% is made up of Carbon Dioxide.
