Answer:
Epithelial Tissue
Explanation:
The epithelial tissue can be classified according to the amount of layers, such as <u>simple epithelium</u> (formed by a single cell layer) or <u>stratified epithelium</u> (formed by more than one cell layer).
In addition, this tissue is avascular, in other words, it has no proper blood supply. Its nutrient transport usually occurs by <u>diffusion</u> through connective tissue.
The epithelium layers are able to regenerate quickly and easily when destroyed. Being a coating tissue, its cells have high healing power.
The epithelial tissue has two opposite sides, the outside of the epithelium(cavity), is known as the <u>apical surface</u>, and the inside is called the <u>basal surface</u> (this surface receives nutrients from the connective tissue by diffusion).
Cells on both surfaces are tightly connected, providing protection to the underlying connective tissue.
Finally, epithelial tissue also participates in the process of absorption of substances through the <u>intestinal epithelium</u>.
