  4. The brain is inside the head. With it we think, remember and order the body to move.

    The heart is in the chest, in the middle and a little to the left. It beats without stopping and pushes the blood all around the body. It is about the size of your fist.

    There are two lungs, one on each side of the heart. They fill with air when you breathe. That is why the chest swells a little.

  5. The stomach is inside the tummy, in the upper part. It receives the food we swallow and starts to break it down. After that, the food goes on its way. It does not stay there for ever.
