surface area of 1 – 2m².
The skin is the largest organ of the body, with a total area of
about 20 square feet. The skin protects us from microbes
and the elements, helps regulate body temperature, and
permits the sensations of touch, heat, and cold.

sebaceous glands
Synthesis function: Suns’s ultra voilet rays help in the synthesis of natural vitamin D.
Water balance: Regulating water balance of the body by perspiration
