All living beings are made up of cells. Some of them are made up of only one cell and others have many cells. The average adult human body has around 37.2 trillion cells. WOW, that's a lot of cells. So many, in fact, that it's hard to picture.
The body is made up from millions of tiny cells. Different parts of the body, such as organs, bones, muscles, skin, and blood, are made up from different specialised cells. All cells have a centre called a nucleus. The nucleus in each cell contains thousands of genes which are made up from a chemical called DNA.
