The integumentary system (the skin, hair, nails and cutaneous glands) works by essentially containing all the inner organs and structures of the body. It has many functions as well besides protection. The cells of the skin are packed with keratin and linked by desmosomes which protect against organisms and water getting in. It also prevents losing too much water and blocks UV radiation. Nerve endings in the skin alerts the brain to temperature, touch and pressure and vasconstriction of blood vessels prevents too much heat loss. It aids in the synthesis of vitamin D and is important in communication especially through facial movements.
from the Latin ; integumentum, which means 'a covering'. So .. skin, hair, nails, scales or feathers, sweat glands. Everything that acts to physically protect the parts inside.
The work done by the system is positive if the system does work on its surroundings, and negative if work is done on the system by the surroundings.

Work done by the system is considered as PositiveWork done on the system is considered as Negative
When a system does work on its surroundings, the sign of work is negative. This is because work done by the system involves energy leaving the system, which decreases its internal energy. In thermodynamics, this is typically represented as ( W < 0 ). Conversely, if work is done on the system by the surroundings, the work is considered positive.
