Anatomy & Physiology

It's time to learn about the human body! As complex as we are, if we have enough background knowledge in chemistry, biochemistry, and biology, it's not all that hard to understand. We know about cells, and the human body is made of different types of tissues, which are just groups of certain kinds of cells. These come together to make organs and systems, all of which serve some pretty miraculous functions. So let's learn about structure, or anatomy, and function, or physiology, so that we are set up to learn all kinds of other subjects that require knowledge of the human body!
