Report Abuse. Smooth muscle tissue is a tissue type. This type is usually found in the walls of the hollow viscera.

Its purpose is to keep organ structure against other forces. It is elastic and easily stretched.
Upon entering the esophagus, peristalsis (wave-like contractions) of smooth muscle carries the bolus toward the stomach. Two layers of smooth muscle, the outer longitudinal (lengthwise) and inner circular, contract rhythmically to squeeze food through the esophagus. Throughout the digestive tract, smooth muscle peristalsis aids in transporting food. From the esophagus, the bolus passes through a sphincter (muscular ring) into the stomach. All sphincters located in the digestive tract help move the digested material in one direction. When the stomach is empty, the walls are folded into rugae (stomach folds), which allow the stomach to expand as more food fills it.
