Structure Of Epithelial Tissue Free Biology Notes Rajus Biology Epithelial tissue is classified based on its cell layers and shape. four main types include: simple epithelium: comprising a single layer of cells, this type is involved in diffusion, absorption, and secretion in locations such as the lining of blood vessels and air sacs in the lungs. stratified epithelium: this type consists of multiple layers. Epithelial tissue is one of the four tissue types. it is found lining the inner and outer body surfaces and comprising the parenchyma of the glands. it is divided into surface (covering) and glandular (secreting) epithelium. surface epithelium consists of one or more cell layers, stacked over a thin basement membrane.

Epithelial Tissue Structure Types And Function With Diagram Free Epithelial tissue definition. epithelial tissues are thin tissues that cover all the exposed surfaces of the body. they form the external skin, the inner lining of the mouth, digestive tract, secretory glands, the lining of hollow parts of every organ such as the heart, lungs, eyes, ears, the urogenital tract, as well as the ventricular system of the brain and central canals of the spinal cord. Epithelial tissue has several important functions that are essential to life. since epithelial cells are found throughout your body, their function and purpose change based on their location. epithelial tissue can have one or a combination of the following several functions: protection: epithelial tissue protects several aspects of your body. Epithelial tissue or epithelium forms the outer covering of the skin and also lines the body cavity. it forms the lining of respiratory, digestive, reproductive and excretory tracts. they perform various functions such as absorption, protection, sensation and secretion. you may like: neet key answer 2022. Epithelial tissue function: epithelial tissues provide the body’s first line of protection from physical, chemical, and biological damage. the cells of an epithelium act as gatekeepers of the body, controlling permeability by allowing selective transfer of materials across its surface. all substances that enter the body must cross an epithelium.

Epithelial tissue is avascular, relying on the blood vessels of the adjacent connective tissue to bring nutrients and remove wastes. the exchange of substances between epithelial tissue and connective tissue occurs by diffusion. innervated. epithelial tissue is innervated; that is, it has its own nerve supply. Classification of epithelial tissues. epithelial tissues are classified according to the shape of the cells and number of the cell layers formed (figure 4.3.2 4.3. 2 ). cell shapes can be squamous (flattened and thin), cuboidal (boxy, as wide as it is tall), or columnar (rectangular, taller than it is wide). similarly, the number of cell layers.
