The oesophagus is a muscular tube, about 25cm long, with a sphincter (valve) at each end. Its function is to transport food and fluid, after being swallowed, from the mouth to the stomach. No absorption of nutrients takes place in the oesophagus. A mouthful of food which has been chewed and swallowed is called a bolus.
The esophagus does not digest the food, but it does the important job of pushing the food down into the stomach as well as keeping it from coming back up into the mouth. Once in the stomach, further digestion takes place.
