ANATOMY

Detailed explanation-1: -Scientists call this little brain the enteric nervous system (ENS). And it’s not so little. The ENS is two thin layers of more than 100 million nerve cells lining your gastrointestinal tract from esophagus to rectum.

Detailed explanation-2: -Anatomy of the brain-gut connection The balance of signals from these two inputs can affect the speed at which food moves through the digestive system, absorption of nutrients, secretion of digestive juices, and level of inflammation in the digestive system.

Detailed explanation-3: -The nervous system controls the digestive system by sending signals to the brain and organs. The brain sends signals to the stomach, intestines, pancreas, liver, and other organs through nerve cells called neurons. Some of these neurons pass on messages from one part of the body to another through electrical impulses.

Detailed explanation-4: -The brain and the endocrine system control digestive processes. The brain controls the responses of hunger and satiety. The endocrine system controls the release of hormones and enzymes required for digestion of food in the digestive tract.
