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.
The wavelike contractions of the smooth muscle in the  gastrointestinal system are called peristalsis. The purpose of  peristalsis is to push boluses of food along the gastr â¦ ointestinal  tract. This is achieved by the waves of contractions in the smooth  muscle followed by relaxation of the muscles, pushing the bolus  (ball of food) a bit further along the digestive tract with each  contraction. These contractions move food or chyme through the  esophagus, and intestines.
