The first peristaltic wave moves the bolus into which segment?

Explanation:
In swallowing, the first wave of esophageal contraction (primary peristalsis) begins as the bolus passes through the upper esophageal sphincter into the esophagus. The initial movement pushes the bolus into the cervical esophagus, the proximal neck segment. The thoracic and abdominal portions come later as the wave continues downstream, and the oral cavity is not part of the esophagus.
