primary swallowing phase
|

|
Gastric mobilization phase

secondary peristalsis

Explanation:
Detailed explanation-1: -During primary peristalsis, the LES is relaxed, starting at the initiation of swallowing and lasting until the peristalsis reaches the LES. Secondary peristaltic contractions are the contraction waves of the circular esophageal muscle occurring in response to esophageal distention.
Detailed explanation-2: -Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.
