muscularis extrena
The Mucosa layer contains lamina propia
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 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 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.
The lamina propria is a layer of connective tissue found underneath the epithelial lining in mucous membranes, such as in the digestive and respiratory tracts. It contains blood vessels, immune cells, and nerve endings, and helps support and nourish the overlying epithelium.
Diegestive secretions are secreated by wich layer of the almentary tube?
Cheek cells
The submucosa layer of the alimentary canal contains loose connective tissue, glands, lymphatic vessels, and nerves. This layer supports the mucosa and helps to transport absorbed nutrients from the digestive tract.
