A Part of Digestive System- The Stomach: parts,functions,condition and diseases

  1. 1. • is an organ between the esophagus and the small intestine lying crosswise in the abdominal cavity beneath the diaphragm • Is a muscular, elastic, pear- shaped bag measuring 12 inches long and 6 inches wide (at its widest point) • Has the capacity to store 1qt or .94 liters in an adult
  2. 2. • It stores swallowed food. • It mixes the food with stomach acids. • Then it sends the mixture on to the small intestine.
  3. 3. •Cardiac/esophageal sphincter- the connection between the stomach and esophagus which prevents food from passing back. •Pyloric sphincter-the connection between the stomach and duodenum with the same role as cardiac sphincter. Chyme- food in the area of duodenum characterized as a semi-solid, soapy mixture.
  4. 4.  Cardia is the first portion of the stomach and is where food content passes from the esophagus into the stomach. The acids and enzymes referred to as the gastric juices are manufactured in the cardia.  Fundus stores undigested food and also the gases released from the chemical digestion of food.  Corpus is the body of the stomach and the largest of the four parts that make up the stomach. This is where the bulk of the partial digestion occurs.  Pylorus is connected to the duodenum or the beginning of the small intestine.
  5. 5. • Mucosa -innermost layer and is where the stomach acid and digestive juices are made • Submucosa -supports mucosa and is surrounded by • Muscularis -a layer of muscle that moves and mixes the stomach contents • Serosa - Covering and the outermost layer of the stomach
  6. 6. •Gastrin ~causes the stomach to produce an acid for dissolving and digesting food •Secretin ~causes the pancreas to send out digestive juice that is rich in bicarbonate •CCK ~causes the pancreas to grow and to produce the enzyms of pancreatic juice.
  7. 7. • Indigestion Also called dyspepsia, indigestion is a term used to describe a feeling of fullness or discomfort during or after a meal. It can be accompanied by burning or pain in the upper stomach. • Gastroesophageal reflux Stomach contents, including acid, can travel backward up the esophagus. There may be no symptoms, or reflux may cause heartburn or coughing. • GERD When symptoms of reflux become bothersome or occur frequently, they’re called GERD.
  8. 8. • Gastric ulcer An erosion in the lining of the stomach, often causing pain and/or bleeding. Gastric ulcers are most often caused by NSAIDs or H. pylori infection. • Peptic ulcer disease Peptic ulcers are holes or breaks in the protective lining of the duodenum or the stomach - areas that come into contact with stomach acids and enzymes. • Zollinger- Ellison syndrome One or more tumors that secrete hormones that lead to increased acid production. Severe GERD and peptic ulcer disease result from this rare disorder
