Lesson 3

Module 8—Circulation, Immunity, and Excretion

Lesson 3—Blood

 

Get Focused

 

So far, you have seen the comparison between the valves, pumps, and pipes of a water treatment plant and the circulatory system. Each of these systems works to move a specific fluid. A water treatment plant circulates water, while the circulatory system pumps blood.

 

As you discovered in previous lessons, water has many unique properties. One property is the ability to dissolve many chemicals, thus allowing the chemicals to be transported in biogeochemical cycles. What special properties of blood allow it to transport matter and energy for metabolic cycles?

 


 

 

In this lesson you will explore the following essential questions:

  • What are the main components of blood? How do these components contribute to transporting, clotting, and resisting the influence of pathogens?

  • How does blood help to regulate body temperature?
