The heaviest organ in the human body is the skin.
According to the provided reference, the skin weighs between four to five kilograms, making it the heaviest organ. The liver is the second heaviest, followed by the brain.
Here's a breakdown of the heaviest organs:
| Rank | Organ | Approximate Mass |
|---|---|---|
| 1 | Skin | 4-5 kg |
| 2 | Liver | (not specified in detail) |
| 3 | Brain | 1.5 kg |
The skin's large surface area and multiple layers contribute to its considerable weight, whereas organs like the liver and brain, despite being crucial, have lesser weight in comparison. The skin's role as the body's outer covering also justifies its substantial mass.
