What is the body structure of a vertebrate?

Vertebrates are characterized by a backbone or spinal column, which is composed of individual vertebrae. This skeletal structure supports the body and protects the spinal cord. Vertebrates also possess a complex internal skeleton made of bone or cartilage, a distinct head containing a brain, and a closed circulatory system. Additionally, they typically have paired limbs and a variety of organ systems that contribute to their overall function and survival.
