Bones are magical
Bones are truly remarkable
It’s function is structural and physiological
It is not a static tissue. It is the most dynamic material in the body.
Bone is a reservoir for calcium and phosphorus.
There is a constant flux of minerals in and out of the bone
Bone responds to injury by rapid healing.
It can be made to grow in different ways
It’s affected by nutritional changes.
Bones are continually being modified, reshaped, remodeled and overhauled
Even when the skeleton is fully matured and there is not more shaping and sculpting to be done, the renewal and removal of bones goes on.
The necessity to maintain structural strength and physiological stability keeps bone an active, changing , growing tissue until the day the organism dies.

We have 206 bones
Bones manufacture blood cells and store minerals
Bones help regulate blood calcium levels
We have 33 individual vertebrae
We have an axial skeleton and an appendicular skeleton
Our vital organs are protected by our skeletal system
Blood cells are produced by the marrow located in bones.
An average of 2.6 million red blood cells are produced each second by the bone marrow to replace those worn out and destroyed by the liver.
When calcium and phosphorus are low in the blood , it will be withdrawn form the bones to replenish the supply.
