Exercise affects lots of different organs in our body. When we exercise we have to breathe faster to ensure our body has enough oxygen to move during exercise.
Here is a video about the respiratory system – it shows how our body takes more oxygen in to help us during exercise.
You could try and make your own respiratory system.
What you will need: Paper, 2 straws, 2 food bags, scissors, sellotape and glue.
Instructions: Draw a nose, a mouth and 2 lungs then cut them out.
Sellotape your 2 straws together (making sure the 2 bendy parts of the straws are at the bottom).
Put one bendy part of one straw into one food bag and wrap sellotape around it to ensure no air can escape. Do the same with the other bendy part of the straw with the other food bag.
Sellotape your nose near the top of your straws (leave enough room for your mouth to blow into the straws), your mouth underneath and then attach your lungs to the back of the straws where the food bags are.
Breathe in and out using the straws and watch the food bags inflate and deflate just like your lungs do when you breathe in and out.
The heart is another organ that has to work harder to help the body exercise. Before you start exercising hold your hand on the left side of your chest and try and feel your heart beat.
Now try this Zumba workout and at the end feel your heart beat again.
Active Apple Man wasn’t too happy that the song was about bananas and not apples ! However he said it was ok because the song helped everyone be active and bananas are a healthy fruit as well. Hope you enjoyed it and had fun.
Does your heart beat feel different ?
Is your heart beating faster or slower?
