Similarities and Difference between Simple and Compound Epithelial Tissue


Simple vs Compound Epithelial Tissue

Simple Epithelium vs Compound Epithelium
(Similarities and Difference between Simple and Compound Epithelial Tissues)

Epithelial tissue is a tissue system in animals that forms the outer layer of body surfaces, the linings of the alimentary canal and the walls of hollow structures. It covers the internal or external surfaces of the body. In the previous post, we have discussed the Structure, Classification and Functions of Epithelial Tissues. Based on the number of cell-layers, the epithelial tissues are classified into Simple Epithelial Tissue and Compound (Stratified) Epithelial Tissue. The present post discusses the Similarities and Differences between Simple and Compound Epithelial Tissues in animals.

What is Epithelium?

Ø  Epithelium is a tissue system in animals.

Ø  Epithelium constitutes the outer layer of body surfaces, linings of the alimentary canal and the walls of hollow structures.

Ø  It covers the internal or external surfaces of the body.

Ø  Epithelial cells are held together by carbohydrate based cementing materials.

Ø  They also possess special junctions between the cells.

Ø  The bottom layer of epithelium is rest on the basement membrane.

Ø  The basement membrane composed of a network of fibrous proteins particularly rich in collagens.

Ø  Epithelial layers are NOT provided with any blood vessels.

Ø  The cells of the epithelium obtain nutrients and oxygen by diffusion from the lymphatic vessels.

Ø  Nerve endings occur in the epithelial tissues for receiving stimuli.

What are the Functions of Epithelial Tissue?

Ø  Epithelium provides protection to the underlying structures.

Ø  Protect organs from injuries by external agencies or pressure.

Ø  Prevent infection by microorganisms.
