im sorry i dont know
The layer of the digestive tract that is composed of stratified and columnar epithelium is the mucosa. This layer is responsible for absorption and secretion in the digestive system.
The layer of the digestive tract that is composed of stratified and columnar epithelium is called the mucosa. This layer is responsible for absorbing nutrients from digested food and protecting the digestive tract from harmful substances.
The gastrointestinal tract contains sphincters, which are circular muscles that regulate the movement of material through the digestive system. Some examples of sphincters in the gastrointestinal tract include the lower esophageal sphincter, pyloric sphincter, and anal sphincter.
The epithelium, lamina propria, and muscularis mucosae are levels of the mucosa, which is the innermost layer of the gastrointestinal (GI) tract. The mucosa is responsible for absorption and secretion.
The layer of the GI tract that functions by secreting a lubricating fluid is the mucosa. The mucosa layer is responsible for producing mucus, which acts as a lubricant to facilitate the movement of food through the digestive system. The mucus also protects the digestive organs from the effects of digestive enzymes and stomach acid.
Sphincters are in the digestive tract and urinary tract. They act as one-way doors to prevent backflow. So once foodstuffs enter the small intestines, it cannot go backward back into the stomach.

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.

The mucosa layer is responsible for producing mucus, which acts as a lubricant to facilitate the movement of food through the digestive system. The mucus also protects the digestive organs from the effects of digestive enzymes and stomach acid.
The epithelial tissue is primarily found in the mucosa layer of the digestive tract. This layer consists of epithelial cells that line the inner surface of the tract, providing a protective barrier and facilitating absorption of nutrients.

The third layer of the digestive system is the muscular layer, known as the muscularis externa. It is responsible for peristalsis, which is the contraction and relaxation of muscles to move food through the digestive system. The muscular layer helps mix and propel food along the digestive tract for digestion and absorption.
The submucosa layer of the digestive tract contains blood vessels, lymph vessels, and nerve cells. These structures play important roles in providing nutrients, removing waste, and coordinating digestive functions within the gastrointestinal tract.
