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
- 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“
