The living framework

Most of your body is soft material,such as muscle,and soft organs,such as the brain or stomach.Without stomach from your 206 skeletal bones,you would be shapeless mass,like a jellyfish.Some of the skeletal bones also have a 2nd important job-they protect other organs of the body. The hard skull bones,for example,protect your all-important brain.Your heart and lungs,which are also vital organs,are protected by the breastboned and by the cage formed by the ribs.The skeleton is a framework,but it's really very different from the framework of a building.Think of how much u've grown since u were born.And you aren't through growing yet!can this rigid skeleton grow with you?indeed it can!Bone is very much alive.Like the other parts of your body,bone has blood vessels and nerves,but it doesn't out as bone.Did somebody ask how it does start out?Well,stay here,i will tell this fascinating history in the next post..thanks!!
