back bona each.
،​

Answer 1

Answer and Explanation:

The rib cage has three important functions: protection, support and respiration. It encloses and protects the heart and lungs. It provides a strong framework onto which the muscles of the shoulder girdle, chest, upper abdomen and back can attach. It is flexible and can expand and contract by the action of the muscles of respiration. The diaphragm is attached to it’s lower border.

The functions of backbone are:-

• Protects the spinal cord and its nerve roots from damage
• It offers points of attachments (fixation) to the various muscles, tendons and ligaments of the back.
• The flexibility of the vertebral column helps in the various movements of the body such as bending forwards, backward and sideways and left and right rotation.
• As all other bones, the vertebrae of the backbone produce red and white blood cells and store vital nutrients, minerals, and lipids.
