The Skeleton
Introduction:
Have you ever wondered how many bones are in the human body, or why do bones break or why there so many? Questions like that only take some time to research and a little determination.
The size and location: There are normally 300+ bones in the human body when born. As time goes on and we grow larger, some of the bones fuse together creating stronger and larger bones. By the time we are fully grown and our bones are done shifting, there are 206 bones left. The bones main function is to support all parts of the body and protect the brain and organs. The skeletons are part of the circulatory system; the bone marrow in the bone helps
to produce red blood cells.
Harm/Diseases: When calcium is lost in the bones the bones release some of the vital calcium that is needed and quickly become weak and brittle, therefore they are easily broken. Fractures can also occur in bones very easily. Bones may be made of strong material, but even tough stuff can break if enough force is applied. When a bone breaks, it is called a fracture. Another type of harm to bones is bone cancer. Cancer that begins in the bone is called primary bone cancer. Primary bone cancer is relatively uncommon in comparison with secondary or metastatic cancer. Metastatic cancer occurs initially in another organ and then spreads to bone tissue.

Neck: Each collar bone is shaped like a rod and slightly like an S. It is horizontal and coherent with the upper end of the breastbone, just above the first rib. The sideways part articulates with the acromium. The collar bones support the shoulder blades in front and keep the shoulder blades back so that the arms can hang on the left and right side of the body. They stop the pectoral girdles from getting out of joints easily and sufficient movement of the shoulders.
Shoulders: The shoulder blade is a flat triangular bone that stretches...
