Here are some things to remember for our test coming up (the date is to be announced in class this coming week).
The muscular system- This system is made up of the muscles and it helps us to move.
The skeletal system- This system is made up of the bones and it helps the body to keep its structure.
Breathing- we breathe in oxygen from the air which then goes to our lungs.
That oxygen is then picked up by the blood that runs through our body.
The blood then brings oxygen to our muscles which use oxygen to make energy.
Without oxygen, the muscle and heart tissue in our body would die.
Digestion- The food that we eat is made up of calories.
Calories are energy.
Our stomach digests the food and the energy is either used by us, stored or wasted by our body.
Hope this helps,
Mr. Goldstein
