The food we eat has to be processed so we can get the nutrients out of it so we can keep our body healthy. This is how the digestive system does this: First you bite the food, the tongue and the teeth chew it.Then it goes through the stomach and it breaks down and churns the food. Then it goes through the small intestines which squeezes it along and absorbs the nutrients in to the body.Then in to the large intestines. The waste is pushed out when you use the toilet.Interesting factsDid you know if your small intestines were uncoiled they would be as long as a bus!JS
The circulatory system is one of the important and fascinating systems of your body. The system takes blood around the body. It is controlled by the heart. The reason you need blood going around your body is because it carries oxygen and nutrients around. The steps of the circulatory system are: The blood enters your heart, then it goes to the right atrium. After that it will travel to the right ventricle, then it is pumped to the lungs, the lungs will add oxygen, it goes back to the heart and it enters the left ventricle, and the blood is pumped to the body, following that it returns to the heart. It is all used to move blood around your body. The veins and arteries carry it.DID YOU KNOW...
