Movements of The Stomach:

September 21st, 2009

 The stomach acts as a temporary reservoir for food, thus allowing the digestive juices time to act on the different food substances.  An ordinary meal takes about five hours to leave the stomach completely.  During this period, the muscles of the stomach churn the food and mix it with water and gastric juice by waves of peristalsis passing from the upper part of the stomach towards the pylorus.  The food, which leaves the stomach to enter the duodenum, is in a semi liquid state and this partially digested food material is called chyme.  It passes into the duodenum in small jets when the pyloric sphincter relaxes and the muscular walls of the stomach contract. medical billing training teaches you all these in detail.
