Your liver has a pretty impressive ability to regenerate.

If part of the liver is removed or damaged, the remaining liver tissue can grow and restore much of the organ's size and function.

But there's an important detail:

It doesn't grow back exactly like a lizard growing a new tail. 😂

Instead, the remaining liver cells can increase in number and the liver can regain much of its original mass.

The liver is also doing a ridiculous number of jobs every day. It helps process nutrients, makes important proteins, stores certain substances and helps the body deal with various chemicals.

So having an organ that can repair and rebuild a significant amount of its tissue is pretty useful.

And no, this doesn't mean the liver is invincible.

Severe or repeated damage can overwhelm its ability to regenerate and can lead to permanent scarring.
