Epithelial Tissue

Epithelial tissue is classified by both cell shape and cell arrangement. Cell shape includes squamous or flat and scale-like, cuboidal which is cube-shaped, and columnar which means that the cells are tall and elongated. The cell arrangement on the other hand can either be simple or stratified, meaning either a single layer of cells or stacked layers. Epithelial tissue is responsible for protection, absorption, filtration, and secretion.


Why is Epithelial Tissue the best type for its location and function?

Epithelial tissue is the best because the amount of layers it consists of can change. When the tissue's role is to protect, it can become stratified and have the required amount of layers for adequate protection. In places such as the kidneys where epithelial tissue is required for filtration, simple epithelial tissue instead of stratified helps to better perform that function. Since epithelial tissue is responsible for lining the surfaces and cavities of your body's organs it is important that it comes in such varieties to suit each different organ's functions to the best of its ability.
