Extrinsic (outside) are nerves from the brain (or spinal cord) to the digestive organ release two chemicals acetylcholine and adrenaline. Acetylcholine helps faster digestion by increasing the contraction of the digestive organs to squeeze with more forcefully and push the food through the digestive tract.he main nerves of the parasympathetic nervous system are the vagus nerves (tenth cranial nerves). PNS originates in the medulla oblongata; other parasympathetic neurons also extend from the brain and from the lower tip of the spinal cord.
Moving food through your digestive tract is another job of your digestive system. Your tongue helps push food to the back of your throat where it can be swallowed. The actions of smooth muscles are what keep the food going through the rest of your digestive tract, which includes your esophagus, stomach, small intestine and large intestine.
