Bolus moves from oral cavity to stomach through the esophagus.
Explanation:
- Bolus can be described as a small mass of food that is chewed in the mouth.
- For further breakdown of the bolus, it has to move from the mouth to the stomach.
- The food passes from the pharynx to the esophagus. The epiglottis prevents the bolus from moving into the trachea.
- The esophagus is the passage from where food passes from the mouth to the stomach.

Explanation:
Once the food bolus enters the esophagus passing the UES, a peristalsis wave carries the bolus down to stomach through the LES. The peristaltic wave consists of two main parts, an initial wave of relaxation that accommodates the bolus, followed by a wave of contraction that propels it.
