Making the world better, one answer at a time. the part of the alimentary canal responsible for peristalsis is the oesophagus or the food pipe.by wave like movements of the smooth muscles on the wall of the food pipe the food is sent to the stomach.he four basic tissue layers of the alimentary canal are: Mucosa, Submucosa, Muscularis externa, and the Serosa.

1 mucosa glands in most parts of the alimentary canal. 2  the lamina propria, which consists of a loose connective tissue supporting the epithelium, and a. 3  muscularis mucosa, which is a double-layer of smooth muscle surrounding the lamina propria.eristalsis, the common waves of contraction that move lumenal contents, come from the contractions of the muscularis externa. The serosa is the outermost tissue layer of those portions of the alimentary canal that are suspended in the peritoneal cavity by mesentery. It is the visceral peritoneum of gross anatomy.
