What Type of Muscle Tissue Causes Peristalsis

Question

What type of muscle tissue causes peristalsis?
A) skeletal muscle
B) smooth muscle
C) cardiac muscle

Accepted Answer

Peristalsis is the coordinated contraction of muscles in the gastrointestinal tract that propels food and waste products along the length of the digestive system. This movement is produced by smooth muscle tissue, which is found in the walls of the digestive tract. Skeletal muscle and cardiac muscle are not involved in the process of peristalsis.
