Connective tissue also known as Fascia.
While it's hard to pin down an exact percentage, fascia makes up a significant portion of your body's mass, with some research suggesting it could be around 17% of total body weight, potentially over 25 pounds in an average adult, though it's a diffuse, continuous network rather than a single organ. It's the ubiquitous connective tissue system wrapping muscles, organs, bones, and nerves, providing support and lubrication.
Key Points About Fascia's Mass:
Significant Weight: Estimates place fascial tissue mass at around 12.5 kg (roughly 27.5 lbs) for an average person, equating to about 17% of total body weight.
Ubiquitous & Interconnected: Fascia isn't one lump but a seamless, body-wide web, making it difficult to quantify precisely as a separate organ.
Composition: Primarily collagen and hyaluronic acid, it's rich in nerve endings, making it a vast sensory organ.
