We are starting a new unit about my body... we know many things... take a look!!!
CIRCULATORY SYSTEM
What is that?
The Circulatory system carries the nutrients from the food we eat and oxygen from the air we breath all around our body, through the blood vessels.

The Circulatory system carries the nutrients from the food we eat and oxygen from the air we breath all around our body, through the blood vessels.
The Circulatory system is formed by the HEART and BLOOD VESSELS.
The HEART beats non-stop like a pump, moving the blood. It is divided into atriums and ventricles
The BLOOD VESSELS carry the blood around the body.These are:
The Arteries carry blood with nutrients and oxigen from the heart to the rest of the body.
The veins carry blood from the body to the heart.
The capillaries conect the veins and arteries.

RESPIRATORY SYSTEM
We breathe in oxygen through our nose,when our diaphragm contracts.
We breathe out carbon dioxide when our diaphragm relaxes.
Step by step
1. We breathe in oxygen through our nose.
2. The oxygen goes down the trachea into our lungs.
3. The oxygen goes through the bronchi and the
bronchioles to the alveoli.
4. The oxygen goes through the alveoli into the capillaries to all our body.
5. The carbon dioxide of our body goes out through our lungs, our trachea and out through our nose.
Here is how it works.....
