Answer :
Answer:
The circulatory system is like a big delivery system inside your body. It's made up of your heart, which is like a pump, and lots of tubes called blood vessels that carry blood all around your body.
Your heart works really hard to pump blood through these tubes. The blood carries important things like oxygen, which we get from the air we breathe, and nutrients, which come from the food we eat. It's like a mail carrier delivering packages to every part of your body!
When the blood has delivered all its packages, it picks up waste products, like carbon dioxide, and takes them back to the lungs so we can breathe them out. This way, our body stays clean and healthy.
Our Circulatory System makes sure every part of our body gets what it needs.
