[单项选择]Anatomy
1. The term anatomy comes from Greek anatomy, "dissection". It is a branch of natural science dealing with the structural organization of living things. The proper understanding of structure, however, implies a knowledge of function in the living organism. Anatomy is therefore almost inseparable from physiology, which is sometimes called functional anatomy.
