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 large, hollow organs of the digestive tract contain a layer of muscle that enables their walls to move. The movement of organ walls can propel food and liquid through the system and also can mix the contents within each organ. Food moves from one organ to the next through muscle action called peristalsis.he large, hollow organs of the digestive tract contain a layer of muscle that enables their walls to move.
