To propel food through the canal (peristalsis)
alimentary canal
smooth muscles are present in alimentary canal
Food is pushed along the alimentary canal by peristalsis, alternating waves of contraction and relaxation in the smooth muscles lining the canal.
Peristalsis - the wavelike motion of the intestinal wall smooth muscles that push the food forward.
the smooth muscles are responsible for perstalsis and segmentation, so that means its the muscularis externa. :)
These fibre do not work according to our will and get tired when overworked. These are found in the alimentary canal. The other name of involuntary muscles is smooth muscle.
The process in which muscles propel food through the alimentary canal is called peristalsis.
The muscular layer, known as the muscularis externa, contracts to facilitate the movement of materials through the alimentary canal. This layer is made up of smooth muscle that helps propel food and waste products through the digestive system via peristalsis.
Seems this best describes the smooth muscle tissue of the alimentary canal (intestines). This is a rather unhurried way to move the food (bolus) through the body to allow nutrients to be absorbed.
The muscular layer responsible for peristalsis in the alimentary canal is the muscularis externa. It is composed of smooth muscle fibers arranged in circular and longitudinal layers that contract and relax to push food along the digestive tract through coordinated movements known as peristalsis.
The anal canal has a ring of muscle, called the anal sphincter
