Esophagus – The Food Transport Tube
The esophagus is a muscular tube that connects the throat to the stomach.
Its main job is to carry food and liquids you swallow into your stomach.
It’s about 25 cm long in adults.
Uses muscle movements (called peristalsis) to push food down.
No digestion happens here — it's only for transport.
Has a valve at the end (lower esophageal sphincter) that prevents food from coming back up.
