The term for the layer of fat that surrounds internal organs and helps regulate body temperature is visceral fat. It is located within the abdominal cavity, where it lies around or between organs such as the intestines, liver, kidneys, and stomach.
Visceral fat is a type of adipose tissue. It cushions and protects organs and also acts as metabolically active tissue, releasing hormones and other signaling molecules. Excess visceral fat is associated with increased risks of cardiovascular disease, type 2 diabetes, and other metabolic conditions.
The temperature-regulation wording describes a general function of body fat, especially insulation provided by adipose tissue. Brown fat is particularly involved in generating heat, while subcutaneous fat lies beneath the skin. However, the anatomical clue—fat surrounding internal organs—specifically identifies visceral fat.
Therefore, “Subcutaneous Fat” is incorrect because it is located under the skin, and “Adipose Tissue” is a broad category rather than the specific anatomical term.
