Human beings are arguably the most complex organisms on this planet. Imagine billions of cells, each with its own identity, working together in an organized manner for the benefit of the total being.
How much does any of us really understand about our body? Human biology is an interesting albeit complicated subject. It is amazing to think that in the entire history of human civilization, we have only started to study about the human body in the last few centuries. Before then, what we knew of the human body was not exactly based on scientific research.
Human biology is an important subject to know about. What could be more important than learning about the organic matter that makes up you? Despite seemingly being an important area of research, very few people develop a large body of knowledge about the human body. To find out if you know a lot about the human body, go ahead and give it your best shot.
