White adipose tissue, commonly known as fat tissue, is a type of connective tissue composed of adipocytes. It has several functions, primarily it is the main long term energy storage organ, but it also functions as an endocrine organ, as a mechanical cushion around the eyes and at the tips of the fingers, and for thermal insulation.
