The basal lamina and the reticular connective tissue underneath. The cells are eukaryotic with a nucleus and membrane-bound organelles. Epithelium consists of closely packed flattened cells that make up the inside or outside lining of body areas.

Excretion Secretion Absorption Diffusion Filtration. There is little intercellular material. Epithelial tissue has a structure known as the basement membrane.

Epithelial tissue covers the outside of the body and lines organs vessels blood and lymph and cavities. For example your skin is made up of epithelial tissue and protects the tissues deeper in your body such as blood vessels muscle and internal organs. Animal cells do not have.

Epithelium occurs in both plants and animals. Skin Hair Nails Sweat Glands. There are several different types of epithelial tissue which form to fulfill specific needs and functions.

And it is the diversity in functions that makes the tissue more significant. Epithelial tissues provide the bodys first line of protection from physical chemical and biological wear and tear. Epithelial tissues have five main characteristics.

All substances that enter the body must cross an epithelium. They perform a variety of functions that include protection secretion absorption excretion filtration diffusion and sensory reception. Polarity all epithelia have an apical surface and a lower attached basal surface that differ in structure and function.

Epithelial Tissue is one of the four types of tissue epithelial muscular connective and nervous in animals which consists of closely aggregated polyhedral cells adhering firmly to one another forming cellular sheets that line the interior of hollow organs and cover the body surface. Epithelial tissues provide the bodys first line of protection from physical chemical and biological damage. Epithelial tissue One of 4 basic tissue types which covers or lines all exposed body surfaces McGraw-Hill Concise Dictionary of Modern Medicine.

Epithelial tissue protects several aspects of your body. An epithelial tissue or epithelium plural is epithelia consists of cells arranged in. Integumentary System Part 2.

It consists of a sheet of tightly packed cells with a minimum of intercellular material and rests upon a non-cellular basement membrane. Eight types of Epithelial Tissue. This is because they cover almost all of our body surfaces.

Detailed Features of Epithelia. Epithelial tissues are thin tissues that cover all the exposed surfaces of the body. Epithelial tissues are animal tissues.

Epithelial tissue - definition of epithelial tissue by The Free Dictionary. Your skin is composed of this tissue and it also lines your body cavities and major organs.
