What is the primary function of subcutaneous fat?

  1. Support and protect organs

  2. Regulate body temperature

  3. Provide moisture to the skin

  4. Generate new skin cells

The correct answer is: Support and protect organs

The primary function of subcutaneous fat is to support and protect organs. This layer of fat, also known as the hypodermis, lies beneath the dermis and serves as a cushion for underlying structures, helping to absorb shock and protect vital organs from injury. Additionally, subcutaneous fat contributes to the overall shape and contour of the body. While regulating body temperature and providing moisture to the skin are important functions related to the skin and its components, these functions are not the main role of subcutaneous fat itself. The body does indeed rely on fat stores for insulation and thermal regulation, but this function is secondary to the protective aspect of subcutaneous fat. Generating new skin cells is a function of the epidermis, specifically involving the basal layer, and is unrelated to the role of subcutaneous fat.
