(ANSWER NEEDED NOW PLS!!) your sister claims that the digestive system works by itself to give your body energy. She states that small branches from the stomach get food to the cells throughout your body. Do you agree with this statement? Why?

I think Yes. Because the stomach is divided into four sections, each of which has different cells and functions. For example the food that you eat contains nutrients that give your body energy. The nutrients from the food consumed should travel from the small branches in your stomach in order to allow the cells to supply the nutrients to the rest of the body.

Could you elaborate?
