The integumentary system is the largest organ system of the body. It forms the anatomic and physical barriers between the external and internal environments and it protects and maintains the internal parts of the body. The integumentary system includes the epidermis, dermis, hypodermis, associated glands, hair, and nails.
The skin is made up of two layers—the superficial epidermis and the deeper dermis. The epidermis is the first line of defense against the external environment and is comprised of four to five layers of stratified squamous epithelial tissue. the dermis is the underlying connective tissue framework that supports the epidermis.
Hair follicles are intricate structutres in the dermis that contains the hair bulb that divides to extend the hair shaft vertically.
The sebacious glands are glands that secretes an oily substance known as sebum which adds a protective layer, prevents fluid loss, and plays a role in antimicrobial activity.
