Oesophagus is a fibromuscular tube, connecting the throat (pharynx) with the abdomen. This fibromuscular tube is approx 25 cm length, and is lined by wet pink tissue known as mucous membrane. The muscular structure runs behind the trachea (trachea) and heart, and before of the spine. simply before coming into the abdomen, the muscular structure passes through the diaphragm. Food is transported through the oesophagus by rhythmic contractions of the muscle (called peristalsis movement) which propagate down the oesophagus. The oesophagus contain sphincters that prevent the entry of air and the reflux of gastric contents respectively. There are two sphincters namely upper and lower oesophageal sphincters.
