Our bodies need nutrients and oxygen.
The circulatory system is a transport system.
It carries nutrients and oxygen around the body.
Nutrientsfrom food.
Oxygenfrom air.
The circulatory system is made up of:
Blood
Heart
Bloodvessels
Blood is a red liquid that travels in theblood vessels.
Blood picksup oxygenand nutrients.
It drops off carbondioxide and waste.
The heart is a muscle.It’s in the middle of your chest.
It pumps blood day and night.
