The CIRCULATORY SYSTEM PROCESS

Our circulatory system pumps blood around our body. 
The blood transports the nutrients and oxygen that we need to 
stay alive. This cycle is called blood circulation.

1.          The heart pumps the blood around the body.
2.          Arteries transport the blood from the heart to the rest of the body.

3.          The blood comes back to the heart through the veins.

4.          Capillaries are tiny tubes that reach where veins and arteries cannot.

THE CIRCULATORY SYSTEM

The DIGESTIVE SYSTEM PROCESS

1.          Inside the mouth, the teeth cut and grind  food, and the tongue mixes it with saliva.

2.          The food goes down the pharynx and esophagus, into the stomach.

3.          The stomach produces gastric juices that turn the food into a kind of paste.

4.          The liver and the pancreas produce substances that mix with the paste.

5.          The small intestine absorbs the nutrients and passes them to the blood.

6.          The substances that we do not need go into the large intestine and out of the body through the anus.
