Question: 1 / 400

What is the primary function of the dermis?

Provides a barrier against pathogens

Nourishes the epidermis

The primary function of the dermis is to nourish the epidermis. The dermis contains blood vessels that supply essential nutrients and oxygen to the epidermis, which is crucial because the epidermis does not have its own blood supply. Without the nourishment from the dermal layer, the epidermis would not be able to maintain its health and vitality, which in turn affects the overall condition and appearance of the skin.

While the dermis also plays roles in other processes—such as housing glands that produce sweat and oil, providing a barrier against pathogens, and participating in temperature regulation—its fundamental role in nourishing the epidermis is key to maintaining skin integrity and function. This supportive relationship between the two skin layers is critical for overall skin health.
