What is the phase of swallowing that involves pushing the bolus of food into the oropharynx?Multiple choice question.voluntarypharyngealesophageal

Breakdown of the Problem

1. Identify the phases of swallowing mentioned in the question.
2. Determine which phase involves actively pushing the bolus into the oropharynx.

Relevant Concepts

• Voluntary Phase: Involves the conscious decision to swallow and moves the food from the mouth to the throat (oropharynx).
• Pharyngeal Phase: Involves reflex actions that push the bolus through the pharynx.
• Esophageal Phase: Involves the movement of the bolus through the esophagus down to the stomach.

Analysis and Detail

1. The voluntary phase is when the bolus is formed and pushed towards the oropharynx by the tongue.
2. The pharyngeal phase is reflexive, where the bolus is propelled through the pharynx to the esophagus after reaching the oropharynx.
3. The esophageal phase deals with the passage of the bolus down the esophagus to the stomach, which is also involuntary.

Verify and Summarize

The question asks specifically about pushing the bolus into the oropharynx. This action occurs during the voluntary phase as the bolus is initially directed towards the throat.

Final Answer

The phase of swallowing that involves pushing the bolus of food into the oropharynx is the voluntary phase.
