How does a bone heal?
Simple.
By a bandage.
No.
Bones are one of the most important parts of our body.
They not only provide structural support but also produce red blood cells.
What?
Our bones produce red blood cells?
Absolutely.
Hence, when we crack or break a bone, it is very important to heal it.
In the healing process, cells called chondrocyte produce collagen which forms cartilage.
This cartilage bridges the gap between the broken bones, thus producing a soft callus.
Then, special cells called osteoblasts create a hard bony callus using collagen and minerals like calcium and phosphorus, thus forming our new bone.
However, this new bone is irregular in shape.
Hence, cells called osteoclasts start remodeling the bone, resulting in the formation of bone similar to the original shape.
