PATHOLOGY

Detailed explanation-1: -Epidermis. The epidermis is the outermost layer of the skin, the layer of skin which is visible. The epidermis is also the thinnest of the three skin layers. It is an avascular skin layer, so it does not contain blood vessels.

Detailed explanation-2: -The epidermis is the outermost part, made of stratified squamous epithelial tissue. So, are there blood vessels in the epidermis? Nope. It’s epithelium and epithelial tissue is avascular.

Detailed explanation-3: -The epidermis is avascular – it has no blood vessels directly in the layer. Veins and arteries are found just deep to the epidermis. Nutrients and oxygen diffuse into this layer from the bloodstream.
