Teachers, save “The Circulatory System” to assign it to your class.

Your task is to annotate this diagram to explain how the circulatory system works. You can use the voice recorder, text and drawing to do this. These questions will help you. Can you describe the functions of the main parts of the circulatory system? Can you label each part and describe how the blood flows around the body? Can you describe what happens at each point? What do the red and blue lines/arrows represent? Can you describe the journey of the blood?
