Mouth: Digestion begins here. Mechanical and chemical digestion occurs here.
Esophagus: A muscular tube that connects the mouth to the stomach.
Peristalsis: muscle contractions that "push" the food down the esophagus.
Stomach: Hollow organ that holds food. Mechanical and chemical digestion occurs here.
Liver: Bile is created here. Bile helps to break down food. Largest organ in the body.
Gall bladder: stores bile until it is needed.
Small Intestines: Nutrients are absorbed into the bloodstream.
Large Intestines: Water is absorbed in the bloodstream.
Pancreas: Produces insulin which helps to break down sugar in the body.
Epiglottis: a flap that covers the trachea when you swallow.
Salivary glands: produce saliva. They also secrete amylase, an enzyme that breaks down starch.
Rectum: final straight portion of the large intestine where waste is stored.
Anus: Where waste leaves the body.

What happens to your food?What happens to your food?
What you need stays in. What you don’t goes out.That’s what digestion’s all about.The food starts in your mouth.The food starts in your mouth.
Your teeth break it up with saliva too,And before you can eat something new,
It’s in your esophagus tube.It’s in your esophagus tube.
Then in your stomach it breaks up againThe food’s so small; what happens then?
To the intestines it rolls.To the intestines it rolls.
For some food the story’s doneBut vitamins and mineral go on a blood run.
Your blood takes what it needs.Your blood takes what it needs
To your bones, skin, brain and heartTo make your body strong and smart.
What happens to your food?What happens to your food?
What you need stays in. What you don’t goes out.That’s what digestion’s all about.

Respiratory systemDigestive system
Respiration takes place in the cells. Respiration is the creation of energy by using glucose (sugar) and oxygen. When the energy is created you also get carbon dioxide and water. These are waste products and the body gets rid of them.
