    Chapter 3: The Integumentary System

    The integument, commonly called skin, forms the outer covering of the body, and functions in
    • Protection,
    • Temperature regulation,
    • Excretion,
    • Sensation,
    • Vitamin D production and
    • Artistic medium for tattoos

    The skin consists of several layers:

    • The surface epithelial layer, the epidermis, and
    • An underlying connective tissue layer, the dermis.
    • The subcutaneous layer (also known as the hypodermis or superficial fascia), is a connective tissue layer attaching skin to structures beneath it.

    Thus, skin is considered an organ, and in fact is the largest organ of the body.
