In this video, Jonathan from the Institute of Human Anatomy delves deep into the often-misunderstood world of fat, scientifically known as adipose tissue. Using detailed cadaver dissections, we explore its critical functions, from energy storage and insulation to heat production and its role as an endocrine organ.

Discover the evolutionary significance of fat for human survival, the fascinating reasons behind body fat differences between sexes, and the unique properties of white and brown fat in adults versus infants. This foundational exploration lays the groundwork for understanding when fat is essential and when it can pose health challenges.
