Considering the fact that a female body can form a fully functioning body inside its womb in 9 months, shouldn’t it be much easier to, suppose, fix a leg injury? Why can it not do the same to repair itself?
In: Biology
It depends on the injury and the way of tissue regeneration. Let’s take the skin for example. A small cut can heal with no/minimal scar tissue because the epidermis(top layer) on both sides of the cut are close and can reconnect. Bigger defects can’t reproduce the same type of tissue and it is replaced with connective tissue(colagen fibers)and the result is a scar. The only structure that can heal with no scars/changes in form and function are bones.
