Skeletal System

This is the Skeletal System. It is the system that protects our vital organs and body parts, it helps us keep our shape and form, because without it we would look like a blob of jelly on the ground. If you look in side a bone, there is bone marrow. Bone Marrow produces blood if there is room for it in our veins. It is a very interesting system, and if you end up breaking a bone, it will heal itself from the middle out, and will fuse together. Overall it's a very important system, and we most likely wouldn't survive without it. The skeletal system can be affected by many diseases. One of the diseases is Arthritis. Arthritis is a group of more than 100 inflammatory diseases that damage joints and their surrounding structures. Arthritis can attack joints, joint capsules, the surrounding tissue, or throughout the body. It usually affects the joints of the neck, shoulders, hands, lower back, hips, or knees. Bone cancer is another disease of the skeletal system. It may originate in the bones or spread there from another part of the body. In the United States, bone cancer accounts for only about 1 percent of cancer cases.
