Storyboard Text

  • Do you want to know how the digestion system works? I am going to explain it to you. Digestion starts at the mouth and ends when there is only waste left over. 
  • It starts in the mouth when the teeth make the food into small bits, and saliva mixes with it. Then the food goes dhows the Esophagus with the help of with peristalsis which is the squeezing motion that pushes the food down. form there your food enters your stomach. The stomach breaks the food down even further, and also mixes the food with enzymes and acids. and form a paste called chyme
  • After that, the food is pushed through into the small intestine. All the nutrients are taken out. Villi grab out the nutrients as the food passes by it. Then the food goes into the large intestine where all the water is absorbed from the food. Meanwhile, before the food enters the small intestine bile and other digestive juices are mixed with the food. The kind of digestive juices that mixes with your food depend on the kind of food that you eat. 
  • So this is how the digestive system works, with a lot of organs helping it. As you can see, your body is always busy, working, and digesting things. The digestive process takes 24 to 36 hours. 
  • Now, whatever food is left over is considered undigested waste. This is stored in the rectum, and then it is discarded. The anus is the opening firm where the undigested waste is discarded. Finally, the digestion process is complete. This who process takes about a day to a day and a half. This process keeps going on over and over gain everytime that you eat anything. 
  • The red is the mouth and salivary glands, then the esophagus, which leads to the grey stomach and purple pancreas. Green is liver and orange is galbladder. blue is small intestine with the appendix attached, and the white is the large one. The appendix is attached to the small intestine but does not have a purpose of which we are aware.
