Human skin is a complex biological organ known as the integumentary system, and the largest in the body, weighing 6-9LB (3-4KG). The skin has two main layers, the upper epidermis, and the lower dermis. These together sit on top of a layer of fat and connective tissue that gives the skin daily support, which contains many different types of cells, some of which produce hair and nail tissue. The skin also plays a number of important roles by providing a physical and biochemical barrier to the outside world protecting us from ultraviolet ( UV ) light from the sun, preventing water loss, and blocking the entry of unwanted microbes and chemicals.


Epidermis is the outer protective layer consisting of tough, flat cells.

The Dermis is a layer containing blood vessels, glands, and nerve endings.

The Hypodermis is deep to the dermis and is also called subcutaneous fascia. It is the deepest layer of skin and contains adipose lobules along with some skin appendages like hair follicles, sensory neurons, and blood vessels.

The hair shaft, is part of the hair that projects above skin surface.

Sweat Pore drops of perspiration ooze from sweat pores on skin surface.

The Vein carries away waste.

The Sebaceous gland produces sebum that protects hair and lubricates the skin.

The sweet gland is a coiled knot of tubes secreting watery sweat.

The Nerve specialized ending at the edge of the epidermis, and other touch sensor types lie at greater depths in the dermis.

The Hair bulb lowest part of the hair, where growth occurs.

The Pores are small openings in the skin that release oils and sweat. 

The Muscle layer 

The Muscle tiny muscle that pulls the hair up when the body is cold.

The Artery

The Adispose tissue


The outer epidermis continually renews and replaces itself with cell division. The basal layer consists of boxlike cells that multiply quickly and gradually move up to the surface, pushed by new cells from below. As the cells travel upward, they develop tiny spines or prickles that blind them together tightly. They then begin to flatten and fill with a waterproofing protein known as keratin. Finally, the cells die and reach the surface fully keratinized, resembling untidy, scalelike, interlocking tiles on a roof. As they flake away with daily wear and tear, more cells arrive from below to replace them.


The skin suffers more physical damage than any other body organ. However, it has fast-acting repair mechanisms for mending small wounds.


It is made up of three layers, the epidermis, dermis, and hypodermis, all three of which vary significantly in their anatomy and function.
