Question

propulsion through the GI tract, contraction and relaxation of adjacent segments of the alimentary canal moves material through the tract

Answer 1

Peristalsis is the process of muscle contraction and relaxation that moves material through the GI tract. It is a wave-like movement that propels food through the tract.

Step-by-step explanation:

Peristalsis is the process of muscle contraction and relaxation that moves material through the gastrointestinal (GI) tract. It is a wave-like movement that propels food through the tract.
