Detailed explanation-1: -It is avascular, which means there are no blood vessels there. The cells in the epidermis get the nutrients they need through diffusion from cells in the dermis, the next layer of the skin. The dermis contains sweat glands, oil glands, hair follicles, blood vessels, and nerve endings.
Detailed explanation-2: -This part of the skin does not contain any blood vessels and is, therefore, dependent on the dermis, which is the layer of the skin located directly underneath the epidermis, to provide access to nutrients and dispose of waste.
Detailed explanation-3: -Like all epithelial tissue, the epithelium is avascular; it has no blood supply of its own. Oxygen and nutrients, however, diffuse into the lower epidermis from the rich supply of blood in the underlying dermis.
