Peristaltic movement

Definition

Peristaltic movement is a coordinated, wave-like contraction of smooth muscles that propels contents through a tubular structure, commonly seen in the digestive system. This process is vital for transporting substances along various biological systems, enabling efficient movement and mixing of materials. Understanding peristaltic movement helps in the design and application of soft robotics, which often mimic these natural mechanisms to achieve flexible and adaptive movement in artificial systems.
