start the breathing system and where you can find you’re BPM (Beats per Minute). In the middle of
your chest is your heart
Heart
Lungs
Liver
Large Intestine
Small Intestine
When you breathe in through your nose it goes round the back of your head/neck and into
your heart which mixes it with blood and gets sent round your body.

Your Blood contains 2 things = Food and oxygen. When you trap your finger in a door your
circulation is stopped so your finger goes numb and/or gets pins and needles. Also you can get your
finger to go Blue in more extreme circumstances.
As our Last bit of the lesson we measured our BPM before and after exercise. Mine started
at 72 BPM and went to 103 BPM. You can easily try it by putting your finger on your neck, finding
you pulse and counting how many beats you have in 1 minute. Retry this procedure after some
exercise, I recommend 2 minutes of:
