Esophagus is the structural aspect that allows food to pass from the mouth to the stomach.

It is an important part of the Digestive System .

Food passes from the Oral Cavity after having minimal absorption.

Breakdown has already been by both mechanical and chemical measures.

During swallowing, the Epiglottis tilts backwards, this prevents food from going into the Lungs.

As the food bolus enters the esophagus it acts as a passageway from the mouth to the Stomach.

No appreciable breakdown or absorption happens at this stage.

Narrow tube that starts at the Pharynx and ends at the Stomach

The wall is made of two smooth muscles 

  • Inner muscle is arranged circularly
  • Outer muscle is arranged longitudinally

Divided into

  • Upper 1/3
  • Middle 1/3
  • Distal 1/3

Food passes through by a process of peristalsis

The junction between the Esophagus and stomach is called “GE junction” or “Gastroesophageal junction
