I read a book that I bought with my mom today. The book is about our bodies. There was a plastic model in the book that explained our bones, digestive system, excretory system, circulatory system, respiratory system and nervous system.
So I explained the digestive system to my mom through the book. I told her this.
Before we intake any kind of food, saliva starts to be activated and our teeth breaks down the food particles and send it through our esophagus. Our esophagus squeezes down the food like the last bit of toothpaste and sends it down to the liver. Then, our liver turns our food into a goo for three hours. That goo goes to a small intestine and the leftovers go to a big intestine. Those leftovers are drained dry and come out as poop. The goo that went to the small intestine provides all the nutrients that will be spread all over the body. Most needed nutrients are fat, protein and carbohydrates.
If we didn’t have a digestive system, what would we be doing with our empty stomachs? We wouldn’t be able to eat food.
Even though the digestive system is invisible to our eyes, it is working hard like a stationery store getting ready for all the kids in the morning.
