Briefly explain why some fat tissue is necessary within the body.

Fat can be divided into two categories:essential fat and storage fat.Essential fat is found within the central nervous system,in bone marrow,and in various organs.Fat is key to normal body functions,including neural transmission and reproductive functioning.Storage fat is further divided into visceral fat and subcutaneous fat.Visceral fat provides cushiony protection for internal organs,and subcutaneous fat helps to insulate the body and regulate body temperature.Storage fat is also a key site for energy storage.
