The oesophagus links the pharynx (throat) and the stomach.
The oesophagus, also known as the gullet, is a muscular tube that plays a crucial role in the digestive system. Its primary function is to transport food and liquids from the pharynx, located at the back of the throat, to the stomach for further digestion.
Here's a breakdown:
- Pharynx: The pharynx acts as a passageway for both air and food. When swallowing, the epiglottis covers the trachea (windpipe) to prevent food from entering the respiratory system, directing it into the oesophagus.
- Oesophagus: The oesophagus uses peristalsis, a series of wave-like muscle contractions, to propel the food bolus (a mass of chewed food) down to the stomach.
- Stomach: The stomach is a muscular organ that further breaks down food through mechanical churning and chemical digestion using stomach acid and enzymes.
Therefore, the oesophagus serves as the essential connection between the pharynx, where swallowing begins, and the stomach, where digestion continues.
