Origin of the word peristalsis

The word "peristalsis" originates from two Greek roots: "peri," meaning "around," and "stallein," meaning "to stand or place." In the 19th century, scientists studying the movement of food through the gut of animals noticed a controlled, wave-like motion in the walls of the intestines. They coined the term "peristalsis" to describe this action, which involves a series of contractions and relaxations in the smooth muscle tissue of the gut. The term has since been adopted to describe similar wavelike movements that occur in other tubular structures in the body, such as the esophagus and uterus.
