Welcome to the amazing world of the circulatory system! This system is like a superhighway in your body, and the heart is the powerful engine that keeps everything moving. The circulatory system’s main job is to deliver blood to every part of your body. To keep it healthy, it’s important to exercise and eat nutritious foods.
The heart is a strong muscle that works like a pump. Every time it beats, it pushes blood all around your body. If you make a fist with your hand, that’s about the size of your heart! It sits in the middle of your chest, just a little to the left.
Now, let’s meet the team that makes up your blood!
Hi there! I’m a red blood cell. My job is to carry oxygen to all the cells in your body. Oxygen is like fuel for your cells, giving them the energy they need to work.
These are white blood cells. They are like tiny soldiers that protect your body by fighting off germs and other foreign invaders.
And these are platelets. They help fix any cuts or injuries by stopping the bleeding and keeping your blood inside your body.
Our journey starts and ends at the heart. Blood travels through special tubes called blood vessels. There are three main types of blood vessels:
Arteries carry blood away from the heart to the rest of your body. They deliver oxygen and nutrients to your organs and cells.
Capillaries are tiny vessels where the exchange of oxygen and nutrients happens. They give your cells what they need and take away waste.
Veins bring the blood back to the heart after it has delivered oxygen and nutrients. They carry waste products like carbon dioxide away from your cells.
Once the blood returns to the heart, it gets ready for another trip around the body. It picks up fresh oxygen and nutrients to start the journey all over again!

Heart Beat Experiment: Find a quiet place and sit down comfortably. Place your hand over your heart and feel your heartbeat. Count how many times your heart beats in one minute. Try doing this after some light exercise, like jumping jacks, and see how the number changes. Discuss with your friends or family why you think your heart beats faster after exercise.
Blood Vessel Maze: Create a simple maze on a piece of paper or use a toy maze. Pretend you are a red blood cell traveling through the circulatory system. Start at the heart and navigate through the arteries, capillaries, and veins. As you move through the maze, think about what your job is at each stage. Share your journey with a friend or family member and explain what happens at each part of the maze.
Healthy Habits Poster: Make a poster that shows ways to keep your circulatory system healthy. Include pictures or drawings of activities like running, jumping, or eating fruits and vegetables. Hang your poster in your room or classroom to remind yourself and others of the importance of taking care of your heart and blood vessels.
Sure! Here’s a sanitized version of the YouTube transcript:

[Music] Welcome to the circulatory system! This is the heart, the driving force of the whole system. The circulatory system brings blood to all parts of your body. It’s important to exercise and eat healthy foods to take care of your circulatory system.
The heart is a muscle, and every beat pushes blood through your entire body. If you close your fist, that’s about how big your heart is—it’s located slightly to the left and in the middle of your chest.
Now that you’ve learned about the heart, let’s see what your blood does!
[Music]
Hi! I’m a red blood cell, and I deliver oxygen to cells, which is their main energy supply. These are white blood cells, and they are responsible for fighting off foreign substances.

These are platelets, and their job is to help repair veins and arteries when you cut yourself. They keep the blood inside where it belongs. Together, we make up blood, the red fluid that comes out when you cut yourself.
Our journey starts and ends in the heart. Blood is delivered to the entire body through blood vessels, which are tubes that transport it. Arteries are the vessels that carry blood from your heart to your organs and cells. Capillaries are small vessels where oxygen and nutrients are exchanged. Veins are the vessels that bring blood back to your heart from your organs.
That’s how cells and organs get the food and oxygen they need to survive. Then, red blood cells take all the waste left by the cells, including carbon dioxide.
Here we are at the heart—this is where our trip ends before we start a new journey. Let’s get loaded up with oxygen and nutrients. Thanks for helping us out! See you soon!
[Applause]
