Every one seems to have it right, it's just a basic pump , it pumps blood around the system, like a central heating system , nothing really very clever about it, all you have to do now is explain what a Central heating system is all about. Good luck !!.

Go to a boating supply store and buy a hand primer for an outboard engine. This will consist of a "squeeze ball" and a length of hose attached to each end of the ball. Put one end of the hose into a jar of water and repeatedly squeeze and release the ball.
The hand primers are inexpensive, by the way. They are also great for siphoning liquids.

More or less, it pumps blood (and oxygen) to all the body in order to keep everything working. Sound simple enough?

Grade One
Students in grade one learn about their body’s systems and various health topics. They begin to understand how their decisions can impact their health and well-being now and in the future. Students begin to relate choices with consequences. They begin to examine the influence of the media on health decisions and to identify ways to access reliable information. They exhibit respect for self, others, and the environment.
Knowledge and Skills
Standard of Learning
1.1 The student will identify the major body systems and explain their connection to personal health. Key concepts/skills include:
a) the cardiovascular system;
Understanding the Standard
The student will identify and understand the importance and function of the cardiovascular system.
Essential Knowledge and Skills.
The student will:
• explain the location and function of the heart. (it is a pump in the center of your chest about the size of your fist and it pumps blood to the whole body)
• describe the function of the blood vessels. (blood travels through your body in blood vessels which are small tubes that take food and oxygen to your body parts)
• describe the function of red blood cells. (these tiny cells carry oxygen to your body parts)
• describe the function of white blood cells. (these tiny cells get rid of any germs that get into your body)
• explain how exercise affects the heart. (when you exercise your heart beats faster to get red blood cells carrying oxygen to your muscles – when your heart beats faster you are also making your heart muscle stronger)
• describe the function of the circulatory system. (your blood vessels carry blood to and from your heart and your body parts)
