The lungs

Hi guys and welcome back to my blog. Today I will be teaching you a little bit about the lungs in your body. For this term we have been learning about the lungs and in this post I will be talking about the lungs and how they work. I hope that you learn something from this blog post

In your body you have 2 lungs. They are protected by your rib cage. Your lungs breathe in O2 which is oxygen and then breathe's out CO2 which is carbon dioxide. We did an experiment about the lungs. Our Teacher Mrs Mclachlan showed us how the lungs would work in your body. These are the steps into making this experiment.

Experiment time

1. First you need to cut a bottle in half
2. Next you need to get some ballons and some straws
3. You then need to tape the ballon to the straw
4. Then you need to put the ballons into the half cut bottle
5. The last thing you need to do is cut a ballon in half and stick it on the bottom of your bottle so that it fits around the bottom of the bottle
6. Once you are finished you can blow threw the straws and watch how the lungs work

Your lungs help you breathe in and out. At the bottom of your lungs you have somthing called a diaphram. When you breathe in your diaphram moves so that your lungs can expand and then when you breathe back in your diaphram goes back into the correct place that it was in before.

Inside your lungs there are these stems. The stems are the things that blow your oxgen into your lungs. You have over 600 of them and if you didn't have them you would die. They are part of your bronchial tube. On the ends of them you have little dots that are called Alveoli.

This is what the inside of your lungs look like.

I hope that you enjoyed learning a little about the lungs. Please comment so I can get points.
