muscles in the chest, abdomen, and pelvis

Explanation:

Swallowing is a process that involves the movement of food or liquid from the mouth to the stomach. The muscles in the mouth help in chewing and forming a bolus. The throat muscles (pharyngeal muscles) then push the bolus into the esophagus. The esophageal muscles (smooth muscles in the esophagus) use peristalsis to move the bolus down to the stomach. Muscles in the eyes, nose, ears (related to facial expressions and sensory functions), arms, legs, back (related to body movement and posture), hands, fingers, wrists (related to hand - related movements), chest, abdomen, pelvis (related to breathing, digestion, and pelvic functions) are not directly involved in the act of swallowing.

Answer:

Muscles in the mouth, throat, and esophagus
