The nervous system interacts with the digestive system in multiple ways. One way is that the medulla, a part of the brain (the brain is the main organ in the nervous system), sends messages to the stomach. The medulla controls survival necesseties. (breathing, heart pulse, blood pressure, etc.) The medulla also controls sending the message to the stomach to churn and digest the food that is in there (it still sends the messageeven if there is not food in the stomach.)

The digestive system also helps the nervous system in many ways. It halps by giving nutrients to the nervous system to make new cell parts if any are damaged. It also helps in a way by giving glucose to the cells. This helps by letting the cells go through cellular respiration. The brain needs this because it goes through a lot of celluar respiration to keep thinking and working through the day. This led me to wonder. I started to think about how this is like the saying, which came first the chicken or the egg? I thought of this because if it weren't for the brain we would be able to digest food in the digestive system, but also the brain needs the glucose from digestion to even send the message from the brain to the stomach to churn and digest the food. So, they need each other to work as systems.
