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.
