Epithelial tissue functions

What are the epithelial tissue functions?

Epithelial tissue functions

The function of epithelial tissue include: It is specialized to form the covering or lining of all internal and external surfaces. It is a made up of many cells that are closely packed with no intercellular spaces.

It is separated from the underlying tissue by a basement membrane. This membrane provides structural support for the epithelial tissue. How can epithelial tissue function in secretion? What are the epithelial tissue functions? It forms the outer covering of the body known as the free surface of the skin.

It also forms the lining of the digestive, respiratory, and urinary tracts; blood and lymph vessels; serous cavities cavities which have no communication with the outside of the body, and whose lining membrane secretes a serous fluidsuch as the peritoneum or pericardium; and tubules small tubes which convey fluids of certain secretory glands, such as the liver and kidneys.

What are the functions of epithelial tissue? Epithelial tissues performs the following functions: Protection Epithelial tissue provides physical protection of exposed structures from: Control permeability Substances that enter or exit the body usually have to travel across an epithelial barrier.

Epithelial tissues may be permeable or selectively permeable only letting certain substances through and not others 3.

Sensation Neuroepithelium is a specialized type of epitheliun with a large sensory nerve supply allowing it to provide sensations such as: Secretion Some epithelial tissue is specialized to produce secretions. What are the classifications of epithelial tissues? Epithelial tissue can be classified by their shape and how they are layered.

Their different shapes are squamouswhich is thin and flat. C uboidalwhich is short, cylindrical, and somewhat cube-shaped.

Functions of Epithelial Tissue

And the last shape is called columnarwhich looks like columns or cylinders. Their different layering arrangements consist of simplewhich is made of one layer of cells. The other is stratifiedwhich is in two or more layers, one stacked above the other, or on the basement layer.Epithelial Tissues types, squamous, cuboidal, columnar Functions of each tissue type and their locations in the body.

Epithelial tissue provides four key functions, they provide protection, they control permeability, they provide sensation, and they produce secretions.

Epithelial tissue functions

Our skin is a great example of an epithelial tissue that protects our body, It is made up of lots of layers of cells. Epithelial tissue also has a sensory function as it contains sensory nerves in areas such as the skin, tongue, nose, and ears.

Ciliated epithelial tissue can be found in areas such as the female reproductive tract and the respiratory tract. Epithelial tissue is a sheet of cells that covers a body surface or lines a body cavity.

Two forms occur in the human body: Two forms occur in the human body: Covering and lining epithelium – forms the outer layer of the skin; lines open cavities of the digestive and respiratory systems; covers the walls of organs of the closed ventral body cavity.

The function of epithelial tissue include: transportation of materials, protection of underlying tissues, absorption of water and nutrients and secretion of waste products. The function of the Epithelial tissue can be:: a, for cover the body surfaces, forms the inner lining of body cavity, and also lines the hollow organs.

b. for regeneration c ells. c, for physical protection from abrasion, dehydration and destruction from chemical and biological substances.
