“Skin”  

    In and on our body's integumentary system, the Skin, the outer covering of the body situated at the interface between the body and the outside environment, is the largest organ composed of a multilayered ectodermal, non-vascularized, stratified squamous epidermal tissue (epidermis) overlying the thick fibrous connective dermal tissue (dermis), which then sits on the hypodermis (subcutaneous tissues) providing a shielding layer for internal organs.

Two Types of Skin

    In and on our body's Skin, there are two types mostly thin and covered with hair follicles, although often appearing hairless and some of our skin is the thick and hairless glabrous skin type.
