Tekst Storyboardowy
- Hello there! I'm Sully the sandwich and I'm going to show you what happens when someone takes a bite of me! It looks like he's about to bite a piece of me!
- Firstly, I enter the mouth. Saliva starts to pump out of the salivary glands and the teeth take a bite of me and chew up the food into a ball called bolus.
- Then, this bolus travels down a long tube down the oesophagus and goes straight to the stomach. The stomach helps make the food even smaller by acids that turn the food into a liquid/solid substance called chyme.
- After the stomach, the chyme now enters the small intestine, a long 'rope-like' organ. Juices from the liver and pancreas help to break down the food even more. The walls of the small intestine contain villi which absorb nutrients.
- These nutrients get sent off to another system in our body, the circulatory system. When the nutrients get sent off into the bloodstream of the circulatory system, essential nutrients needed for our body parts are delivered there.
- It's kinda like the digestive system prepares the nutrients for delivery so that the circulatory system can take the package to the important organ. This is a vital process needed for our bodies. These two systems work together to support vital organs needed and their collaboration together is essential for the human body!
- When the waste finally reaches the rectum, the part expands and nerves tell the body that it's time to go to the toilet. FInally, the waste leaves the body through the anus.
- After the long ride in the small intestine, all the stuff left goes to the colon or large intestine. The walls drain remaining fluid left and the rest of the waste goes all the way to the rectum to exit.
- Finally, the journey is done. The digestive system helps to get essential nutrients into our body and helps to get rid of waste. WIth the help of other systems, this process is essential to the human body.
- Ooh! It looks like he's going to take another bite! See ya next time!
