We are born with over 300 bones, and when we grow into an adult we have 206. The cell that breaks down bone is osteoblast and the stuff that build bones is osteoclast.

Osteoclasts are cells that break down and absorb bone tissue back into the body. ... an osteoclast is now known as one of two primary cell types the human body uses in ... Osteoblasts are the cells that actually create bone; osteoclasts are the cells ... They are highly specialized cells that must work.

osteoblast ostoclast you are born with 300 and when you grow you get 206 bones in your body

ALice M. said...

Osteoblast builds up bone when it broken, and creates a lump, then, when the bone is fully healed, osteoclast breaks down the lump so the bone is even again.
When a baby is born, it is born with 300 bones, then over time the bones fuse together and make new bones. A full-grown adult has 206 bones in their body.

osteoblast builds up bone and osteoclast breaks down bone and we are born with 300 bones and they all fuse together to make 206 bones in the human body as an adult.

Emily B. said...

the two cells are called ostoblast and osteoclast. when we are born we have 300 bones in our body but as we grow into adult hood some bones fuse together and we then have about 206.

Jasmine B said...

The cell in our body that builds up bones is called osteoblasts, and the cell that breaks down bones is called osteoclasts.
We are born with about 300+ bones in our bodies, but when we grow up and the bones fuse together, we have about 206 bones in our bodies
