Question

what muscle type is responsible for peristalsis?
cardiac
skeletal
voluntary
smooth
rewatch

Explanation:

Peristalsis is the involuntary contraction and relaxation of muscles that helps move substances (like food in the digestive tract). Cardiac muscle is specific to the heart. Skeletal muscle is voluntary (e.g., moving limbs). Voluntary muscle is the same as skeletal muscle in this context. Smooth muscle is involuntary and lines internal organs (like the digestive tract), enabling peristalsis.

Answer:

smooth
