Detailed explanation-1: -Protects and supports organs: Your skull shields your brain, your ribs protect your heart and lungs, and your backbone protects your spine.
Detailed explanation-2: -Bones also protect internal organs from injury by covering or surrounding them. For example, your ribs protect your lungs and heart, the bones of your vertebral column (spine) protect your spinal cord, and the bones of your cranium (skull) protect your brain (see Figure 6.1.
Detailed explanation-3: -Axial skeleton: The main purpose of the axial skeleton is to provide protection for the central nervous system (brain and spinal cord) and vital organs, such as the heart and lungs. It is also the structure that provides the support and attachment for your arms and legs.
Detailed explanation-4: -Protection – the bones of the skeleton protect the internal organs and reduce the risk of injury on impact. For example, the cranium protects the brain, the ribs offer protection to the heart and lungs, the vertebrae protect the spinal cord and the pelvis offers protection to the sensitive reproductive organs.
Detailed explanation-5: -Skeletal system gives support and shape to our body. Without the skeletal system, the body will be a limp mass of organs, muscle, and skin. Bones facilitate movement by serving as points of attachment for the muscles.
