Introduction to the lesson
So far in the biology course, we have studied how the body is supposed to work. In the last chapter we began to see some cases of how the gas exchange system can be broken by pathogens, particularly those found in cigarette smoking. In this chapter we will study five infectious diseases. We will learn how they are caused, how they are treated and how the spread of these diseases can be controlled. In the next chapter we will explore the immune system and see how the body itself is made to combat infection. This lesson is an overview of the content that will be covered in the chapter.
