why our skin and liver, the largest organs in our body, regenerate but other organs can’t?
In: 335
Most organs regenerate to some degree, some more than others. Still the regeneration isn’t perfect. Scarring usually occurs or the regenerated tissue is not exactly like the damaged one. Sure livers regenerate and they become as big as they were but that doesn’t mean their functional capacity is the same. Bones heal too, and muscles and ligaments but often injury to those means chronic complications and their full capacity may never be regained. It’s the same with skin. Sure a paper cut heals pretty well but serious injury to skin leaves scars and often nerve damage and partial or complete loss of sensation.
