The dermis is vascular. It contains a network of blood vessels that supply nutrients and oxygen to the skin and play a crucial role in temperature regulation.
The dermis is the layer of skin located beneath the epidermis and is composed of connective tissue. This layer is rich in blood vessels, lymphatics, nerves, hair follicles, and sweat glands. The blood vessels in the dermis provide essential functions such as delivering oxygen and nutrients to the skin cells and removing waste products.
In contrast, the epidermis, which is the outermost layer of skin, is avascular, meaning it does not contain blood vessels. Instead, it receives nutrients through diffusion from the underlying dermis. The presence of blood vessels in the dermis is essential for maintaining skin health and promoting healing.
