How does a bone repair itself?

Answer 1

there are actually bacteria in your bone that constantly eat it away and enzymes that constantly build it back up. When you have a break, the bacteria stop eating the bone and the enzymes have an opportunity to build it uninhibited. This actually means that where you had your break eventually there will be a mass of bone much larger than normal. When this happens, the bacteria are then reintroduced and allowed to eat at the bone until all returns to normal. This being in an average small break.

Answer 2

If a bone is broken, it should be aligned in such a way that the broken ends are close together. They will make new bone the way that they made bone as a fetus and a child. They will form a cartilage bridge between the ends and then replace the cartilage with new bone. The bone also over-grows and forms a callus.This is sort of like a cast would be and adds strength to the growing bones. The process takes awhile to be complete. If this bone is weight-bearing (leg or foot), a person must stay off of it for at least 8 weeks. The callus slowly is reabsorbed.

Answer 3

Yes they can. And if you have a broken leg or arm, it's important to have a lot of calcium so your bones can heal faster

Answer 4

our body has special cells called 'osteoblast cells' which repair the bone.

Answer 5

through protein joinging up into much larger molecules that are stronger with then join onto the bone

Answer 6

65 in a human body fix themselves
