ELI5: Why does the liver have so much more regenerative properties than other organs?
gpt
Firstly, the liver is not a mechanical organ like the heart or kidneys. It’s functions are based entirely on chemistry, not on structure. Any liver cell anywhere can do what a liver cell does. So, if you remove a piece of the liver, the liver still works. This would not work for a mechanical organ like the heart, because the structure of the heart is absolutely key to how the heart functions. If you remove a piece of the heart, you fundamentally alter its mechanical properties.  

Secondly, the liver is primarily tasked with de-toxifying toxic chemicals, and so it is constantly exposed to toxic chemicals. This constant exposure to toxins causes constant damage to liver cells. So liver cells have to constantly replace themselves as they become injured or killed in the line of duty. 

Put these two facts together (the shape and placement of liver tissue is irrelevant and liver tissue has a high rate of cellular regeneration), and it adds up to the fact that the liver can regenerate itself far beyond what most other organs are capable of.
