Concept Explanation
 

Oesophagus

Food pipe or Oesophagus: It connects mouth to the stomach and runs along neck and chest. It carries slightly digested food from the mouth to the stomach. Food is pushed downward by a wave like movement of the wall of food pipe as a result of alternate contraction and relaxation. This movement is called peristalsis. The chewed food enters the esophagus from mouth and is passed down to stomach is called bolus. Sometimes, food is not accepted by our stomach and is vomited out because the food moves in the opposite direction, i.e. from stomach to mouth by anti – peristaltic movement in esophagus. Our windpipe and food pipe runs adjacent to each other. Air and food share a common passage in the throat. When we swallow food, a flap like valve closes the passage of the windpipe and guides the food into the food pipe. But if we laugh or talk while eating, the windpipe remains open and food particle enters into the windpipe and we experience hiccups, cough or choking sensation.
