Hidden Facts About the Liver You Might Not Know

The liver, the second-largest organ in the human body, is vital for numerous bodily functions. It aids in metabolism, fat burning, and weight regulation. Positioned above the stomach beneath the diaphragm, roughly the size of a football, it’s well-known for some features but hides many interesting facts. Here are some lesser-known insights about this incredible organ:

Unique ability to regenerate

The liver can regenerate itself, even after substantial damage, needing only a quarter of its tissue to restore full function, thanks to evolutionary mechanisms that safeguard this process.

Master detoxifier

The liver filters toxins from everything we consume, breaking down harmful substances with enzymes and oxygen. It then neutralizes leftover toxins by combining them with amino acids, which are eliminated via urine or bile.

Performs multiple functions

Recognized as one of the most complex organs, the liver performs hundreds of essential roles, including:

Synthesizing vital plasma proteins

Processing hemoglobin to retrieve iron

Removing drugs and poisons from the bloodstream

Converting ammonia into urea for excretion

Ancient civilizations revered it

Ancient Greeks believed the liver was the seat of pleasure, reflected in its Greek name, “hepar,” meaning joy and human emotion. Mesopotamians also attributed emotional significance to this organ.

Crucial for blood development

During fetal development, the liver and spleen are primary sites for blood cell and platelet formation, emphasizing its role in hematopoiesis.

Early transplants faced failure

The first attempt at human liver transplantation in 1963 by Thomas Starzl ended in failure, with patients not surviving past three weeks, following initial studies on dogs in 1958.

Liver health impacts brain function

A healthy liver efficiently removes toxins, protecting the brain from damage. Liver failure can lead to hepatic encephalopathy, which may cause coma.

Livers are found in all vertebrates

Beyond humans, all vertebrates possess livers. For instance, the basking shark’s liver can account for up to 25% of its total body weight, showcasing its importance across species.
