What is the most inner part of a bone?
bone marrowThe innermost part of a bone contains the bone marrow. The layer of compact bone surrounds an interior cavity called the medullary cavity.
Which bones protect lungs?
A bony cage (commonly called the rib cage), which is formed by the sternum, ribs, and spine, protects the lungs and other organs in the chest. The 12 pairs of ribs curve around the chest from the back. Each pair is joined to the bones (vertebrae) of the spine.
Which organ is protected by skull?
the brainBones also protect the body’s organs. The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column.
Which organ is not protected by the rib cage?
The liver is located under the ribs on the right hand side of the body. It lies just below the lungs, under the top of the diaphragm to which it is attached. The diaphragm is the muscle beneath the lungs which regulates our breathing. The liver is partly protected by the rib cage.

Which organs are protected by rib cage?
The ribs are connected to the sternum with a strong, somewhat flexible material called cartilage. The rib cage help protects the organs in the chest, such as the heart and lungs, from damage.
What organs does the skeletal system consist of?
Humans are vertebrates, animals having a vertabral column or backbone. They rely on a sturdy internal frame that is centered on a prominent spine. The human skeletal system consists of bones, cartilage, ligaments and tendons and accounts for about 20 percent of the body weight.
