Epithelial Tissue - Definition, types, functions, examples.
Epithelial Tissue Definition Epithelial tissues are thin tissues that cover all the exposed surfaces of the body.
Typically epithelial tissue is classified on the basis of arrangement and shape of cells. For naming the tissue types, the arrangement of the cells is stated first, then the shape, and is followed by “epithelium” to complete the naming. For example; Simple Squamous Epithelium. 1.
Types of epithelial tissue. There are 3 different types of epithelial tissue: squamous, cuboidal, and columnar. The differentiation and classification of the types of epithelial tissue are based on the shape of the cell (e.g., cuboidal), the arrangement (e.g., single-layered) and the cell surface (e.g., by kinocilia in the respiratory epithelium).
Well, epithelial tissue is one of the must abundant tissue types in the body. It's one of the human body's four classifications of tissue. The others are connective, muscle and nervous tissue. You'll find epithelial tissue in every organ in your body.
Epithelial Tissue: There are three principal classifications associated with epithelial cells. Squamous epithelium has cells that are wider than they are tall. Cuboidal epithelium has cells whose height and width are approximately the same. Columnar epithelium has cells taller than they are wide.
Epithelial tissue, or epithelium, has the following general characteristics: Epithelium consists of closely packed, flattened cells that make up the inside or outside lining of body areas. There is little intercellular material. The tissue is avascular, meaning without blood vessels.
Epithelial tissue, the type of tissue that lines the surfaces and cavities of your body's organs, is no different. Epithelial tissue is like the brand name Lego: Lego has differently sized and.
Epithelial tissue covers the outside of the body and lines organs, vessels (blood and lymph), and cavities.Epithelial cells form the thin layer of cells known as the endothelium, which is contiguous with the inner tissue lining of organs such as the brain, lungs, skin, and heart.The free surface of epithelial tissue is usually exposed to fluid or the air, while the bottom surface is attached.

Epithelial Tissue. Epithelial tissues are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands. They perform a variety of functions that include protection, secretion, absorption, excretion, filtration, diffusion, and sensory reception. The cells in epithelial tissue are tightly packed together.
