How is the movement of food through the esophagus most accurately characterized? Multiple Choice Gravity is necessary to move food toward the stomach. Skeletal muscle is the main muscle type around the esophagus. Nutrients are absorbed in the esophagus. The muscular contractions are entirely involuntary. The muscular contractions are wave-like.

Smooth muscle is one of the primary components of the esophagus. This muscle experiences involuntary, wavelike contractions that help move the food from the proximal end (throat) to the distal end (stomach). This is called peristalsis. It is possible, although not recommended, to eat while lying down because gravity does not aid in the movement of food through the esophagus. What would happen if the smooth muscle tissue that makes up the esophagus was not functioning properly? How would this affect the early stages of digestion?
