Which structure protects vital organs in the body?

• A. Skin
• B. Skeleton
• C. Cartilage
• D. Muscles

Answer: (B)

Protection of vital organs comes mainly from a rigid protective framework that forms enclosing shells for them. The skull shields the brain, the rib cage guards the heart and lungs, and the vertebral column protects the spinal cord. Bones are strong and capable of withstanding impacts, which is why this structure is best for safeguarding internal organs. The skin acts as a barrier against infection and dehydration but does not enclose organs. Cartilage provides cushioning in joints and some support, but it doesn’t form the protective enclosure that bones do. Muscles can help shield organs by padding and by supporting the body, but their primary role is movement and maintaining posture, not direct protection like a skeleton.
