Detailed explanation-1: -The epidermis does not contain blood vessels; instead, cells in the deepest layers are nourished by diffusion from blood capillaries that are present in the upper layers of the dermis.

Detailed explanation-3: -The cornea is the only living tissue in the human body that does not contain any blood vessels.
