Explanation:
Different Types of Disease
A nation can be broken apart from two very general directions. It can be attacked from the outside, as in a foreign military, or it can break down from within, as in internal economic collapse or revolution.
Similarly, your body can suffer from poor health as a result of a) external factors or b) internal malfunctions. By external factors, I largely mean infectious disease--those caused by viruses, bacteria, fungi, and parasites. These are organisms that come in from the outside (from the environment), make their way into your body and cause you all sorts of problems.
This lesson isn't about that, however. It's about diseases caused by internal malfunctions--when your body revolts against you without, necessarily, any outside cause.
