Burn grade is determined through, among other things, the size of the skin affected. The image shows the makeup of different body parts, to help assess burn size. The size of a burn is measured as a percentage of total body surface area (TBSA) affected by partial thickness or full thickness burns. [ 2 ]
The study of human physiology as a medical field originates in classical Greece, at the time of Hippocrates (late 5th century BC).
