Verified step by step guidance

Understand the process of swallowing, which is divided into three main phases: oral phase, pharyngeal phase, and esophageal phase.

Recognize that the oral phase is the first phase of swallowing and is voluntary, meaning it is under conscious control.

Learn that during the oral phase, the tongue and other muscles in the mouth work to move the bolus (chewed food mixed with saliva) from the oral cavity into the oropharynx.

Differentiate the oral phase from the pharyngeal phase, which is involuntary and involves the movement of the bolus through the pharynx, and the esophageal phase, which involves the bolus moving down the esophagus.

Conclude that the correct phase involving the voluntary movement of the bolus from the mouth into the oropharynx is the oral phase.
