How is our liver able to regenerate itself, when our other organs cannot?

Many other organs can regenerate. For example, skin, bones, blood vessels.

But liver is the only internal (visceral) organ that can regenerate.

The reason for this is that the main function of liver is to remove ingested toxins from blood before they reach main circulation, and liver cells are relatively often killed off in that process. (Because toxins are, well, toxic.)

Most other organs have no strong need to replenish their cells, and as a result they are unable to recover from a significant loss. But again, organs that *do* have a strong need to replenish their cells (like skin) can (and do) regenerate from significant damage.
