Epithelial Tissue covers body surfaces (epi‚ on + thelium‚ surface). Epithelial tissue consists of cells attached to one another to form an uninterrupted layer of cells that separates the underlying tissues from the outside world. The body’s epithelium not only covers its obvious surfaces (such as the epidermis of the skin and the linings of respiratory‚ urinary‚ and digestive tracts) but also extends into all of the complex invaginations which form lungs‚ kidneys‚ sweat glands‚ digestive glands

and external body surfaces. Epithelial tissue can be divided into two groups depending on the number of layers of which it is composes. Epithelial tissue which is only one cell thick is known as simple epithelium. If it is two or more cells thick such as the skin‚ it is known as stratified epithelium.

understanding of how the human body is able to function as a unit. The human body is composed of four basic types of tissues such as epithelium ‚ connective ‚ muscular ‚ and nervous tissues. These tissues vary in their composition and their function. A basic understanding of the role of each tissue makes understanding the specific functions easier. Epithelium is lines and covers surfaces. Connective tissues to protect‚ support‚ and bind together. Muscular tissue produces movement and Nervous

Epithelial Tissue (or epithelium) is a sheet of cells that covers a body surface or lines a body cavity Forms boundaries Occurs in the body as covering and lining epithelium and glandular epithelium Covering and lining epithelium forms the outer layer of the skin‚ and lines the open cavities of the cardiovascular‚ digestive‚ and respiratory systems‚ and covers the walls and organs of the ventral body cavity (internal and external surfaces) Glandular epithelium fashions the glands of

viewed the specimen and be very detailed in your sketch. Epithelial Tissue Background Functions of Epithelium Epithelium has two major functions: covering/lining and glandular: Epithelial tissue covers body structures or lines body spaces. One side of the epithelium is free (not attached) because it either faces outward (skin) or inward (lining). The other side of the epithelium is called the basement membrane and is attached to underlying connective tissue. Epithelia do not have

Epithelial Tissue * Epithelial tissue or an epithelium‚ is a sheet of cells that covers a body surface or lines a body cavity * It occurs in the body in two ways 1. Covering and lining epithelium- Forms outer layer of skin and lines organs 2. Glandular epithelium- fashions glands of body (secretion) * Functions 1. Protection 2. Absorption 3. Filtration 4. Excretion 5. Secretion 6. Sensory Reception -The epithelium of the skin protects underlying tissues from
