- Epithelial tissue - to cover the inner and outer surfaces of the stomach The stomach is one of the organs that form the digestive system. The stomach contains various tissues, and each tissue is made of a particular type of cell. In order of increasing size and complexity: cells → tissues → organ (the stomach) → organ system (the digestive system)

- Why does the stomach have tissue? the stomach needs the muscle tissue and the elastic tissue to stretch and digest the food. Connective Tissue: Is the blood in the walls of the stomach. Nervous Tissue: Contr…ols acid production in the stomach. It also helps contract and coordinate stomach muscle. Epithelial Tissue: Protects the stomach against acid. It covers the inside of the stomach.

The differences between epithelial tissue, connective tissue, muscular tissue and nervous tissue? Best Answer: Hello, -The epithelial tissue or epithelium in dermatology is a tissue composed of a layer of cells. In humans, it is one of four primary body tissues.Epithelium lines both the outside (skin) and the inside cavities and lumen of bodies. The outermost layer of our skin is composed of dead stratified squamous epithelial cells, as are the mucous membranes lining the inside of mouths and body cavities.ther epithelial cells line the insides of the lungs, the gastrointestinal tract, the reproductive and urinary tracts, and make up the exocrine and endocrine glands. Functions of epithelial cells include secretion, absorption, protection, transcellular transport, sensation detection, and selective permeability.

- Of course, the wall of the bladder has several layers of cells of different tissue types, of which the transitional cell epithelium is the innermost or most superficial relative to its urinary surface. Deep to this layer is a layer of muscle cells, which make up the muscular layer of the bladder wall.s urine flows out of the bladder and through the urethra (the urine passage through the penis), the bladder empties. The inside of the bladder is covered by a smooth glistening water-tight surface of tissue known as mucosa.

Precancerous conditions of the stomach Gastric epithelial dysplasia. Gastric epithelial dysplasia occurs when the cells of the stomach lining (mucosa) become abnormal. These abnormal cells may eventually progress to adenocarcinoma, the most common type of stomach cancer.Gastric epithelial dysplasia can be divided into 2 types: 1  low-grade dysplasia.astric adenoma. Gastric adenoma (adenomatous gastric polyp) is a type of polyp made up of abnormal (atypical) glandular cells from the stomach lining. They are found in areas of the stomach where the normal tissue has been changed by chronic inflammation.

Epithelial Tissue & functions, types of epithelia in digestive tract Epithelial Tissue & functions, types of epithelia in digestive tract. Epithelial Tissue. Epithelium is an animal tissue and is one of the four basic types of tissues in animal. These tissues cover the structures in the whole body and line cavities. They also form different types of glands.Selective absorption, secretion, transport across cells, protection and detecting sensation are its functions.his tissue has cells that are clustered tightly. This tissue is avascular which implies that it should get nourishment through the diffusion of the substances from the connective tissue that is underlying via basement membrane. Types of Epithelia in Digestive tract. Epithelium lines up the digestive tube.

What is epithelial tissue? Epithelial tissue forms the inner lining of the stomach, lungs, and blood vessels. Types of epithelial tissue There are different types of epithelial tissue, distinguished by the different shapes of their constituent cells: squamous, cuboidal, and columnar. Squamous (pavement) epithelium consists of flattened cells.

Epithelial Tissue Skin cells as well as those that line the stomach and intestines are continually being replaced. Surprisingly, then, epithelial tissue lacks blood vessels and must get its nutrients from underlying connective tissues. Because epithelial tissue covers surfaces and lines cavities, it always has a free surface. The other surface is attached to underlying tissue by a layer of carbohydrates and proteins called the basement membrane. Epithelial tissues are classified according to the shape of the cells and the number of cell layers.

Introduction to the Stomach  (Digestive System) The pylonic sphincter is also called the  pyloric valve  and is the route by which the contents of the stomach is squeezed out of the stomach as chyme, passing into the first part of the small intestine-called the duodenum. The outlet (from the stomach) itself is called the pyloric outlet.The walls of the stomach consist of several layers of different types of tissues. Due to their complexity, these structures are best represented by a series of diagrams illustrating the individual layers.bove: Simple diagram of areas of the stomach (incl. adjoining oesophagus above and duodenum below). 1  The upper (which may also be called the  superior ) part of the stomach extends, and is connected to, the oesophagus.
