Here's how it works:

* Digestion: The digestive system breaks down food into smaller molecules that can be absorbed.

* Absorption: The small intestine absorbs these nutrients, along with water and vitamins.

* Bloodstream: The absorbed nutrients enter the bloodstream, which is a network of vessels that transports blood throughout the body.

* Delivery: The blood carries the nutrients to all the cells in the body, where they are used for energy, growth, and repair.

So, while the digestive system does the initial breakdown, it's the blood that acts as the delivery service, ensuring every cell gets the nourishment it needs!
