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. From outer to inner: serosa, external muscle layer consisting of  outer circular and inner longitudinal, submucosa and mucous  membrane. 28 people found this useful.

Describe the structure and function of alimentary canal? Each region of the alimentary canal has it own function and different structure. There are 4 basic layers in the wall of the alimentary canal. Working from the inside these are: a) the mucosa b) the submucosa c) the muscularis externa d) the serosa.he serosa is a very thin layer, made up of connective tissue covered with a single layer of thin, smooth closely fitting cells. en833i2424lnnq We can observe in detail each part of the human alimentary canal structure in this diagram.

Human Physiology/The gastrointestinal system The digestive system is made up by the alimentary canal, or the digestive tract, and other abdominal organs that play a part in digestion such as the liver and the pancreas. The alimentary canal is the long tube of organs that runs from the mouth (where the food enters) to the anus (where indigestible waste leaves).uscularis: 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.

- The basic structure of the alimentary canal, including its four basic layers. In certain regions of the alimentary canal, the mucosa may perform one or all three of these functions. Digestive mucosa is made up of three sublayers: (1) a lining epithelium, (2) a lamina propria, and (3) a musclularis mucosae.

What term describes a series a wavelike contractions of the smooth muscles in a single direction? The wavelike contractions of the smooth muscle in the gastrointestinal system are called peristalsis. The purpose of peristalsis is to push boluses of food along the gastrointestinal tract. This is achieved by the waves of contractions in the smooth muscle followed by relaxation of the muscles, pushing the bolus (ball of food) a bit further along the digestive tract with each contraction. These contractions move food or chyme through the esophagus, and intestines.

Muscular layer In the ureter the smooth muscle orientation is opposite that of the GI tract. There is an inner longitudinal and an outer circular layer. The inner layer of the muscularis externa forms a sphincter at two locations of the gastrointestinal tract: 1  in the pylorus of the stomach, it forms the pyloric sphincter. 2  in the anal canal, it forms the internal anal sphincter.

- The layer in the innermost part of the digestive tract is called the mucosa. The mucosa serves to line the cavity of the tract. The mucosa consists of three sub-layers called the epithelium, the lamina propria, and the muscularis mucosae.

Digestive System: Histology of the Alimentary Canal The mucosa (also known as mucus membrane) is the innermost layer of tissue. It’s a moist epithilial membrane that lines the alimentary canal lumen from mouth to the anus. The mucosa has three major functions: 1  Secrete mucus, digestive enzymes, and hormones. 2  Absorb the end products of digestion into the blood.3  Protect against infectious disease.he basic structure of the alimentary canal, including its four basic layers. In certain regions of the alimentary canal, the mucosa may perform one or all three of these functions.

- Are the same nerves responsible for peristalsis in the smooth muscle of the esophageal body and relaxation of the LES ? Presently, there is evidence that noncholinergic inhibitory nerves and cholinergic and noncholinergic excitatory nerves are involved in peristalsis in the esophageal body.

Alimentary Sentence Examples The visceral commissure, while still surrounding the digestive tract, becomes looped; its right half, with its proper ganglion, passes to the left side over the dorsal face of the alimentary canal (whence the name supra-intestinal), while the left half passes below towards the right side, thus originating the name infra-intestinal given to this half and to its ganglion.

Peristalsis The ridge in the upper part of the picture is the high pressure of the upper esophageal sphincter which only opens for a short time to let water pass. Peristalsis is a radially symmetrical contraction and relaxation of muscles that propagates in a wave down a tube, in an anterograde direction.he large intestine does not use peristalsis to propel its contents, but general contractions. These occur one to three times per day in the large intestines and colon, and propel the chyme from the large intestine through the colon to the rectum.

Review Control of peristalsis in the smooth muscle segment of the esophagus is more complicated than in the adjacent striated muscle segment. In the latter, the central nervous system not only initiates the primary and secondary peristaltic wave, but also completely controls the sequential nature of the contraction.n addition, sequential contraction of longitudinal muscle also occurs during peristalsis. This serves to shorten the esophagus and increase the cross-sectional diameter, thereby facilitating bolus transport.

- The digestive system of an ascarid consists of four parts: Alimentary Canal, Mouth, Pharynx, and Intestine. The alimentary canal compromises a short pharynx or esophagus representing the foregut, a long intestine or mod-gut, and a short rectum or hind gut.he stomodeum consists of the “mouth and lips”, buccal cavity, and the pharynx (esophagus). Each of these regions are used extensively in taxonomy as well as classification of nematodes, and for providing as indication of feeding habit or trophic group.

The large intestine is the portion of the digestive system most responsible for absorption of water from the indigestible residue of food. The ileocecal valve of the ileum (small intestine) passes material into the large intestine at the cecum.
