The oesophagus, also known as the esophagus, is a muscular tube that carries food and liquids from the throat to the stomach. It is approximately 25-30 cm (10-12 inches) long in adults and is lined with mucous membranes that help to lubricate and protect it from the acidic digestive juices. The muscles in the oesophagus contract and relax in a wave-like motion, known as peristalsis, to propel food and liquids into the stomach for digestion.
