Week 10 - Cells

4. Introduction to Human Body Systems

Lesson 8: Introduction to Human Body Systems

By the time you have completed this set of lessons you will be able to interpret the healthy function of body systems, and illustrate ways in which the body reacts to internal and external stimuli.

In the first two lessons you learned about cell structure and function. In this lesson we are going to look at the human body and the structure and function of many of the organ systems found in it. People have been trying to find out about how the body works for a least two thousand years. In the past this has been a very risky business. People caught 'mucking around' inside dead bodies have been jailed or even burned at the stake. But we won't do that to you just for studying.

You will be just learning an introduction to human body systems. But, if you take biology in high school, you will continue to learn more and more. Perhaps it will even lead you into careers in medicine or physiology, the chemical and biological study of living systems.

Well, we're off to see how the body works!
