Muscularis: The muscularis is responsible for segmental contractions and peristaltic movement in the GI tract. The muscularis is composed of two layers of muscle: an inner circular and outer longitudinal layer of smooth muscle.
Peristalsis is the contractions and the relaxations made by the muscles of the body especially by the muscles of the alimentary canal. Peristalsis is important for the movemenâ¦t of food through the oesophagus (so that the food can reach the stomach) and the large intestine (for prevention of constipation).
