The oesophagus, also known as the esophagus or food pipe, is a muscular tube that connects your mouth to your stomach. It's a crucial part of your digestive system, responsible for transporting food and liquids from your throat to your stomach.
Function and Anatomy of the Oesophagus
- The oesophagus is a hollow, muscular tube.
- Its muscular walls contract (squeeze) to propel food downwards towards the stomach.
- A valve called the lower esophageal sphincter (LES) is located at the junction of the oesophagus and the stomach, preventing stomach acid from flowing back into the oesophagus.
- The oesophagus is approximately 25 cm (10 inches) long in adults.
- It lies behind the trachea (windpipe) and heart, passing through the diaphragm before emptying into the stomach.
The Oesophagus in the Digestive System
The oesophagus is one of the hollow organs that make up the gastrointestinal (GI) tract. This tract includes the mouth, esophagus, stomach, small intestine, large intestine, and anus. The oesophagus plays a vital role in the process of digestion by efficiently transporting food to the stomach for further processing. The coordinated contractions of the esophageal muscles ensure the smooth passage of food.
Clinical Significance
Conditions affecting the oesophagus, such as esophageal cancer, reflux, and other disorders highlight the importance of this organ in maintaining digestive health.
