The dermis is also home to hair follicles, sweat glands, blood vessels and the outer layer of our nerves. The blood vessels are responsible for the supply of oxygen to the epidermis layer and they also take waste products (toxins) away to be processed and expelled from the body.
Follicles are tubular shaped. Some of them contain hair, and some are empty. They deliver moisture from the sweat glands. They also allow sebum from sebaceous glands to travel to the surface of the skin. On the skin’s surface the follicle opening is seen and known as a pore.
subcutaneous layer or hypodermis
The subcutaneous layer is made up of blood vessels, nerves and adipose cells. The adipose cells are what are known as fat-filled cells. These fat-filled cells exist to protect the bones and to keep us warm. They also store fat as an energy reserve.
