CIRCULATORY SYSTEM:

PARTS:

• HEART – Atriums and venticles.

• ARTERIES

So…

• The circulatory system moves blood through the heart and around the body in the arteries and veins. Blood gives us nutrients and oxygen.

RESPIRATORY SYSTEM

PARTS:- NOSE- MOUTH- LUNGS

IMPORTANT WORDS:- OXYGEN- CARBON DIOXIDE.

SO…

The respiratory system helps us breathe.

We breathe in air through the nose and mouth.

The air goes to the lungs.

Oxygen is passed to the circulatory system.

We breathe in oxygen. We breathe out carbon dioxide

DIGESTIVE SYSTEM

• PARTS:

- MOUTH

- STOMACH

- INTESTINE- Large/Small.

So…

The digestive system helps us digest food.

We take food through the mouth.

It goes down into our stomach and intestine.

The intestine separate the nutrients from the waste and expel the waste.
