Circulatory System

The system of the heart, blood, and blood vessels, it moves oxygen, nutrients and waste
Real World Example
Imagine trying to organize and deliver packages throughout a bustling city efficiently. This scenario is similar to how the circulatory system in our body operates. Just as a delivery system uses roads (blood vessels) to transport packages (oxygen and nutrients) from a central hub (the heart) to various addresses (body cells) and collects waste (used packages) for disposal, the circulatory system ensures that each part of your body gets what it needs to function while removing what it doesn't need.
