What is the primary function of subcutaneous fat?
- To protect internal organs from injury

Study Notes
Locations of Fat
- Subcutaneous fat lies just beneath the skin and can be seen from the outside.
- Visceral fat lies deep within the abdominal cavity and surrounds organs such as the stomach, liver, and intestines.
Functions of Fat
- Subcutaneous fat serves as an energy reserve and is generally harmless.
- Visceral fat releases fatty acids, hormones, and inflammatory substances directly into the portal vein, which leads to the liver, posing health risks.
Health Implications
- Visceral fat has direct venous drainage to the liver through the portal vein, providing direct hepatic access to free fatty acids.
- Subcutaneous fat has venous drainage through systemic veins, which does not pose the same health risks as visceral fat.
Endocrine Regulation
- Visceral fat plays a role in endocrine regulation, with factors expressed and released by adipose tissue.
Key Differences
- Subcutaneous fat is harmless and serves as an energy reserve, while visceral fat can endanger health due to its release of harmful substances into the portal vein.
