Which of the following is a function of bone in the human body?

• A. Support and protection of organs
• B. Absorption of nutrients
• C. Regulation of hormone levels
• D. Production of digestive enzymes

Answer: (A)

Verified step by step guidance

1. Understand the primary functions of bones in the human body. Bones are part of the skeletal system and play key roles such as providing structural support, protecting vital organs, enabling movement, storing minerals, and housing bone marrow for blood cell production.
2. Eliminate options that are unrelated to the skeletal system. For example, absorption of nutrients and production of digestive enzymes are functions of the digestive system, not the skeletal system.
3. Consider the role of bones in hormone regulation. While bones do interact with hormones (e.g., calcium regulation via parathyroid hormone), they do not directly regulate hormone levels. This option can be excluded.
4. Focus on the correct function: support and protection of organs. Bones like the rib cage protect the heart and lungs, while the skull protects the brain. Additionally, bones provide a framework for the body, supporting muscles and tissues.
5. Conclude that the correct answer is 'Support and protection of organs,' as this aligns with the primary functions of bones in the human body.
