The digestive system acts in stages to digest our food.Each stage is important and prepares the food for the next stage.
Did you know that the entire digestive system is 20 to 30 feet long!
The digestive system breaks down our food to give us energy.It starts in our mouth with the teeth.The food then travels down the oesophagus into the stomach.From there it passes into the intestines.what then happens is it left passes out through the rectum.
The teeth are the first part of the digestive system
You have two sets of teeth in your lifetime - milk teeth and adult teeth. Your 20 milk teeth fall out and you get replaced with 32 adult teeth.its important to brush your teeth twice a day , once in the morning and the second time is at night.
Teeth are the white thing in your mouth which help you chew and eat your food properly.
We have 4 types of teeth in our mouth, they are called incisors,canines, premolars and molars.
Incisors: We have 8 incisors when we have adult teeth.They are sharp and are used for biting off food.
Premolars and molars: We have 8 premolars and molars.
Canines: We have 4 canines. Canines are pointed and are used for tearing and gripping food.
The stomach is an important part of the digestive system.Once the food reaches the stomach, it will remain there for about 4 hours.while it is there, enzymes break down the food.Muscles in the stomach squeeze in ripples to churn up the food.
