Here's how it works:
* Digestion: When we eat, our digestive system breaks down food into smaller molecules that our body can absorb.
* Absorption: These smaller molecules are absorbed into the bloodstream from the small intestine.
* Circulation: The blood, pumped by the heart, carries these nutrients throughout the body.
* Delivery: Blood vessels reach every cell in our body, delivering the nutrients they need to function.
So, the blood acts like a delivery service, bringing the essential nutrients from our food to every cell in our body!
