In the composition of every organ and component of the nine bodies, there is a wonderful calculation of safety, use of energy as well as need. The body has hard bones to maintain support and shape. There are 203 bones in an adult human body, including 3 in both hands, 4 in legs, 2 in skull, 12 in face, 2 in ribs and 2 in spine.
Bones are made up of about 60 percent calcium, 21 percent oxygen, and 15 percent phosphorus. Its cavity has a bone marrow where blood particles are formed.
The skeleton is not just a support but is useful in all activities such as walking and lifting weights. The bones of the body are connected to each other by 20 joints. These joints are also shaped as needed. The joints of the elbows and knees are like hinges that can be turned to one side. The shoulder bones are like a scalpel and a cane that can be rotated around. The bones of the spine are entwined in the nerve cord in the same way that beads are entwined in a nest.
