What is the Circulatory System?

The circulatory system is responsible for moving blood, oxygen, and nutrients throughout the body. It works continuously to deliver what cells need to stay healthy while carrying away waste products.

The three parts featured in this worksheet are:

• Heart – the muscular organ that pumps blood around the body.
• Arteries – blood vessels that carry blood away from the heart.
• Veins – blood vessels that return blood back to the heart.

By learning these three key parts first, students build a strong foundation for understanding how the circulatory system keeps the body alive and healthy.
