Integumentary system
Make it clearer
The integumentary system brings together the skin and its appendages: hair, nails, sebaceous glands, and sweat glands with their ducts. Beneath the dermis lies the hypodermis, subcutaneous tissue that is associated with the system but is not strictly part of the skin.
Picture a boundary built from different layers and parts, not a single sheet. Together, the skin and its appendages form the body's outer covering.
In brief
The integumentary system includes the skin and its appendages: hair, nails, sebaceous glands, and sweat glands with their ducts. The hypodermis lies below the dermis and is described as subcutaneous tissue functionally associated with the skin, not strictly as part of the skin.
Together, the components of the integumentary system form the body's outer covering. This boundary is made up of the skin and its appendages, rather than a single uniform layer.
