Verified step by step guidance

Step 1: Begin by identifying the anatomical structure in question, which is the vertebral column. Recall that the vertebral column is a series of interconnected bones (vertebrae) that form the backbone.

Step 2: Understand the primary function of the vertebral column. It serves as a protective structure for the spinal cord, which is a vital part of the central nervous system. Additionally, it provides structural support for the body, allowing for upright posture and movement.

Step 3: Evaluate the options provided in the question. Eliminate choices that do not align with the known functions of the vertebral column. For example, filtering waste products from the blood is a function of the kidneys, not the vertebral column.

Step 4: Further eliminate options that describe functions unrelated to the vertebral column, such as hormone production (a function of endocrine glands like the thyroid) or gas exchange (a function of the respiratory system, specifically the lungs).

Step 5: Conclude that the correct answer is the option describing the vertebral column's role in supporting and protecting the spinal cord while providing structural support for the body, as this aligns with its anatomical and physiological functions.
