Answer 1

Answer:

Nerve endings occur in epithelium but blood vessels do not.

Explanation:

Epithelial layer:

Among four tissue types of the body epithelial layer is one of them. epithelial layer is present around surface of all organs including skin, reproductive, respiratory and digestive tracts. Epithelial cells lack vessels, it means that they do not contain any blood vessels, These cells receive nourishment through the process of diffusion of substances from the underlying connective tissue,

Nerve endings are present inside Epithelial tissue, so that they feel pain when ever something cuts these layer.
