About This Dataset

Human Body's Major Organs by Average Weight

The major organs of the human body ranked by average weight in grams. The skin is technically the largest organ by weight at approximately 4,000 grams — far heavier than the liver which is the heaviest internal organ. The human brain weighs approximately 1,400 grams but consumes about 20% of the body's total energy.

Analysis

Skin heads the table on 4,000, ahead of Liver (1,560) and Brain (1,400) in Average Organ Weight (grams). 3,900 separates the highest figure (4,000) from the lowest (100). Most of that gap is between first and second alone (2,440 of 3,900); the other 7 are separated by just 1,460. Only 1 of the 8 reaches even half the leader's figure (2,000 or more).
