Fatty tissue, a kind of fibrous connective tissue containing a large number of fat-filled cells, serves several critical functions in the body. According to the provided reference, the three main functions are:
- Energy Storage
- Hormone Production
- Acting as a Shock Absorber and Insulator
Detailed Breakdown of Fatty Tissue Functions
Energy Storage
Fatty tissue's primary role is storing energy. Excess calories are converted into fat and stored within fat cells (adipocytes). This stored fat can then be mobilized and used as fuel when energy demands increase or when caloric intake is insufficient.
Hormone Production
Fatty tissue is now recognized as an active endocrine organ, meaning it produces and secretes hormones that influence various physiological processes. These hormones, also called adipokines, play a role in:
- Appetite regulation
- Insulin sensitivity
- Inflammation
Shock Absorption and Insulation
Fatty tissue also acts as a physical cushion, protecting internal organs from injury. This is particularly important around organs like the kidneys. Furthermore, it provides insulation, helping to regulate body temperature by reducing heat loss.
