WHAT WE HAVE LEARNED
1. The body is made of five things: water, albumin, fat, sugar, and minerals.
2. Water is mixed with all parts of the body.
3. Albumin makes the living part of each cell.
4. Fat is in pockets between the cells. It warms the cells and keeps them from being hurt.
5. Sugar is made from starch. It warms the body.
