What skin layer is devoid of blood vessels?

Epidermis
Dermis
Subcutaneous
Hypodermis

The correct answer is: Epidermis

The epidermis is the outermost layer of the skin and is known for being devoid of blood vessels. Instead, it receives nutrients and oxygen from the underlying dermis through diffusion. This layer is primarily composed of keratinocytes, which create a protective barrier, and it plays a crucial role in the skin's protective functions, including the prevention of water loss and the warding off of pathogens. In contrast, the dermis contains a rich supply of blood vessels that provide nourishment to the skin and help regulate temperature through the flow of blood. The subcutaneous layer, also known as the hypodermis, is located beneath the dermis and consists of loose connective tissue and fat, with blood vessels present within its structure. Thus, the clear distinction of the epidermis as the layer lacking blood vessels highlights its unique role in the overall dermatological system.
