Lesson one: human digestive system

If you look to your body you will find that it consists of many organs that work together in harmony as your legs, arms, eyes, heart, and stomach nose and so on

in general the body of any living organism consists of

Group of systems ^{which in turn consists of group of} Organs ^{which in turn consists of group of} Tissues

^{which in turn consists of group of} Cells ^{which in turn may be} animal cell ^or plant cell
