The Antireflux BARRIER  Lower Esophageal Sphincter (LES).  Esophageal Acid Clearance.  Epithelial Resistance.  Upper Esophgeal Sphincter.

The lower Esophageal Sphincter Anatomic Factors: Anatomic Factors: Diaphragm “muscle sling”. Cardiac angle. Intra-abdominal Esophageal segment. Phrenoesophageal ligment (H.H). Neural Innervation: Neural Innervation: Causing relaxation of LES during swallowing. Hormonal factors: Hormonal factors: Gastrin increase LES pressure.
