When most people hear the word "obesity," they only think about a number on a scale. But in anatomy and physiology, the real story is what that excess adipose tissue is doing to the environment your organs live in. Obesity isn’t just extra weight sitting there—it’s a biologically active tissue that shifts your internal chemistry, affecting everything from blood pressure and insulin signaling to the physical structure of your heart and liver.
In this video, Jonathan from the Institute of Human Anatomy uses real cadaver dissections to show you the difference between subcutaneous and visceral fat, and how that "hidden" fat deep inside the abdomen crowds and compromises your internal organs. We explore why the heart has to work harder even at rest, how the liver becomes a "processing center" under siege, and the physiological breaking point of the pancreas.

Common Questions:
What is the difference between subcutaneous and visceral fat? Subcutaneous fat sits just under the skin, while visceral fat accumulates deep around your internal organs and is more metabolically active/inflammatory.
Can fatty liver disease be reversed? Yes, early stages of fat accumulation and inflammation can often be reversed with lifestyle changes and weight loss.
How does obesity cause high blood pressure? Increased tissue requires more blood flow, increasing cardiac output, while inflammatory signals from fat cells cause blood vessels to constrict.
Is BMI a perfect metric? No, it can be misleading for people with high muscle mass, but for the general population, it is a reliable indicator of excess adipose tissue.
