lesson 2: The circulatory system
The circulatory system is the life support system that feeds your cells with food and oxygen. It also takes away the waste products. The circulatory system is like a network of highways, streets and alleys connecting all the cells together into a community.
There are three main parts to the circulatory system. These are the heart, the blood vessels and the blood.
Pointers to Remember:
the blood vessels
the pig's heart
OBJECTIVES OF THE LESSON:
At the end of this lesson, learners are expected to demonstrate an understanding of: (1) how the different structures of the circulatory and respiratory systems work together to transport oxygen-rich blood and nutrients to the different parts of the body; and (2) the prevention, detection, and treatment of diseases affecting the circulatory and respiratory systems.
