Introduction

The Human Body is Awesome and Complex

By Andreas Vesalius - Bijzondere collectie Universiteit van Amsterdam

The human body is composed of many levels of organization functioning together to maintain life processes. The simplest is the cell of which you have about 100 trillion.

This lesson will look at these organizational levels from the simplest cell to the most complex of the levels: the human. Highlights of this lesson will be:

• the 5 levels of organization,
• an overview of the 4 tissue types found in your body, and
• an overview of the 11 organ systems within your body.

If you want, take a look at the different organ systems viewed in 3D at Zygote Body.
