So we've been talking about the skeletal system, and, you know, the important thing to remember is that the skeletal system is regularly regenerating.

You know, you build a desk, you know, out of wood, but then you're setting stuff on it and you're moving it from one apartment to another.
00:22
You know, that desk might start to break or crack or start to squeak and, you know, eventually it may fall apart.
00:32
The human body is amazing.
00:33
And so we don't want to have our bones break and crack and fall apart and us not be able to move and do the things we need to do.
00:42
And so our body does something called bone remodeling.
00:48
And bone remodeling has multiple functions to help our body to perform.
00:56
And one of those reasons for bone remodeling you can imagine is to repair.
01:02
Right and so it will take old and brittle pieces of bone that you know have gotten maybe worn out and could cause us problems and it'll break them down and the cells that do that as you may have read before are called osteoclasts and that's different from osteoblasts which make the new bone and so the osteoclasts we'll take the old and brittle bones and make it go away, and then the osteoblasts will come along and make the new bone in its place.
01:45
And so it will replace that old brittle bone with new bone.
01:51
Another reason that bone remodeling, sorry about that happens, is potentially to reshape or repair.
02:07
Reshape or heal bone that could have stress be putting on it...
