Which phase is voluntary?

Explanation:
The first stage of swallowing is under voluntary control. In this oral phase you consciously prepare the bolus, chew, form a cohesive lump, seal the lips, and propel the bolus to the back of the mouth with the tongue. Once the bolus reaches the oropharynx, the pharyngeal stage takes over as an automatic reflex to protect the airway and move the bolus downward. The final esophageal stage is also automatic, driven by peristaltic waves. So, the only phase you actively initiate and control is the oral phase.
