Explanation: Doedunum is a hollow tube that forms part of the digestive tract. It is attached to the pyloric sphincter of the stomach and to the jejunum of the small intestine, that way it plays a huge role in receiving chyme(food) from the stomach and pass it to the small intestine for absorption. Food in the doedunum is taken as signal that initiate enzymatic digestion. Pancreatic juices, bile salts and other enzymes enter the doedunum when it a receives signal that there is food that needs to be digested, broken down by enzymes, then passed on to the jejunum for absorption.
