The body is made of these five things.
Fat tissue (×100).
The liquid fat is stored in living pockets.
6. Albumin.—Second, next to water, something like the white of an egg makes the most of the body. The white of an egg is albumin. When dried it is like gelatine or glue. Albumin makes the most of the solid part of each cell. Lean meat and cheese are nearly all albumin. When it is heated it becomes harder and turns white. The word albumin means white. Dry albumin is hard and tough, but in the living cells it is dissolved in water and is soft like meat. It is the only living substance in the body, and it alone gives it strength.
7. Fat.—Third, next to albumin, the most of the body is fat. Fat does not grow inside the cells of the body, but it fills little pockets between the cells. Fat does not give strength. It makes the body round and handsome. It also makes the cells warm and keeps them from getting hurt.
8. Sugar.—Fourth, sugar also is found in the body. Sugar is made out of starch. When we eat starch it changes to sugar. Starch and sugar are much alike. We eat a great deal of starch and sugar, but they are soon used in warming the body. Only a little is in the body at once.
9. Minerals.—Fifth, there are also some minerals in the body. When flesh is burned they are left as ashes. Salt, lime, iron, soda, and potash are all found in the body.
