Why is backbone formed of many ring like bony paces?

The backbone, or vertebral column, is formed of many ring-like bony structures called vertebrae, which provide flexibility and strength to the spine. These vertebrae are stacked on top of each other, allowing for a wide range of motion, while their ring-like shape helps to protect the spinal cord that runs through the central cavity of each vertebra. This design also enables the spine to absorb shocks and distribute weight evenly, contributing to overall stability and support for the body.
