High Quality Content by WIKIPEDIA articles! The Tree of physiology is a Tibetan Thangka depicting human physiology and certain pathological transformations. Tibetan medicine had developed a rather sophisticated knowledge of anatomy and physiology, which was acquired from their long-standing experience with human dissection. Tibetans out of necessity, had long ago adopted the practice of celestial burial (also Sky burial) because of Tibet's harsh terrain in most of the year and deficit of wood for cremation. This form of Sky burial, still practiced, begins with a ritual dissection of the deceased, and then followed by the feeding of the parts to Vultures on the hill tops. Both the location of the ritual dissection and the place of feeding is understood as the charnel ground.
