@Anna32 - Anatomy, as you read above, is more the study of the body's parts from a structural level. Physiology, on the other hand is the study of how the body's parts and systems work, both independently and interactively.
For example, if you were to look at a human anatomy diagram, you might gain a bit of understanding about the different organs, bones, and muscles in the body, but not necessarily what they do or how they work. For that information you would need to study physiology. Hope that helps!
