Oesophagus
The oesophagus, also known as the food pipe, is a muscular tube about 25 centimeters long that connects the throat (pharynx) to the stomach. Its primary function is to transport swallowed food and liquids from the mouth to the stomach for digestion. When you swallow, muscles in the oesophagus contract rhythmically in a process called peristalsis, pushing the food downward. The oesophagus is lined with a protective mucous membrane and has a ring-like muscle at its lower end to prevent stomach acids from flowing back, helping prevent acid reflux. It plays a vital role in the digestive process.
