Your body is like a big team, with each part having a special job to do. Your legs and feet help you walk and run, while your nose lets you smell yummy food or fresh flowers. Your ears are great at helping you hear music and voices.
Inside your body, there are important parts that you can’t see, but they work hard to keep you healthy. One of these parts is your heart. Your heart is a strong muscle that sits a little to the left in your chest. It never takes a break because it has a very important job: pumping blood all around your body!
Your heart pumps blood through tiny tubes called blood vessels. There are two main types of blood vessels: arteries and veins. Arteries are like highways that carry blood away from your heart to the rest of your body. Veins are like roads that bring blood back to your heart.
Your heart, blood vessels, and blood all work together as a team called the circulatory system. This system is super important because it helps move oxygen and nutrients to where your body needs them. It also helps take away things your body doesn’t need anymore.
The circulatory system is not alone! It works with other systems in your body to help you grow, play, and stay healthy. For example, it works with your lungs to get oxygen into your blood and with your digestive system to get nutrients from the food you eat.
Isn’t it amazing how your body works together like a team to keep you healthy and strong?
Heart Beat Experiment: Find a quiet place and sit down comfortably. Place your hand over your heart and close your eyes. Can you feel your heart beating? Count how many times your heart beats in one minute. Try this after doing some jumping jacks or running in place for a minute. What do you notice about your heart rate before and after exercise? Discuss why you think your heart beats faster when you move around.
Blood Vessel Maze: Draw a simple maze on a piece of paper. Pretend this maze is like the blood vessels in your body. Use a small toy car or a marble to navigate through the maze. As you move through the maze, imagine you are blood traveling through arteries and veins. Think about how your heart helps push you through the maze. What happens if you get stuck? How does your heart help keep the blood moving?
Oxygen and Nutrients Relay: Gather some friends or family members and play a relay game. Use a small ball or beanbag to represent oxygen and nutrients. One person starts as the heart and passes the ball to the next person, who is an artery. Continue passing the ball around, representing blood moving through the body. Once the ball reaches the last person, who is a vein, they bring it back to the heart. Discuss how this game shows the way your circulatory system works to deliver oxygen and nutrients throughout your body.

Your body is made up of different parts, and these parts help your body in various ways. Your legs and feet assist you in walking and running, while your nose helps you to smell. Your ears enable you to hear sounds around you.
There are also different parts inside your body that work together to support its functions. One special part that never stops working is your heart. The heart is a muscle located slightly to the left of your chest. It pumps blood throughout the body via tiny tubes called blood vessels. The heart receives blood from your body and sends it to and from the lungs.
There are two types of blood vessels: arteries and veins. Blood travels away from your heart through arteries and returns to your heart through veins. The heart, blood vessels, and blood function together as a system known as the circulatory system.
