Unit D

Module 7 ~ Lesson 3


The blood has both cellular and non-cellular components that contribute to the transport of gases, protection from blood loss, and protection from pathogens. Each cellular component of the blood has a specific function in maintaining homeostasis. The abundance of each type of blood cell can assist medical professionals in diagnosing and treating a variety of disorders.

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?
