Air precedes the bolus into the open UES. As the bolus flows through the UES it begins to slow down as frictional forces begin to play an increasingly dominant role. The subatmospheric pressure disappears as the bolus moves into the esophagus. Flow is now 30 to 60 cm/sec. Pressure and inertia are still dominant, but friction assumes greater importance. As the bolus moves from the UES into the esophagus, it rapidly decelerates and slows to 2 to 4 cm/sec. The stripping wave transforms into a peristaltic wave as rapid change gives way to slow change.
