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.

The RESPIRATORY SYSTEM PROCESS

1.          We breathe in air through our nose and mouth.
2.          The pharynx opens and the air goes down a tube called trachea.
3.          The air travels through two tubes called bronchi and enters the lungs.
4.          The OXYGEN from the air passes from the lungs into our blood.
5.          When we breathe out, CARBON DIOXIDE leaves our lungs.
