What is the main function of long bones?

• A. Protect vital organs
• B. Support columns for the body
• C. Diffuse concussion and diminish friction
• D. Facilitate blood cell production

Answer: (B)

Long bones primarily serve the function of supporting and providing structure to the body. They act as columns that help maintain an upright posture and mobility, enabling movement in conjunction with muscles and joints. These bones are typically found in the limbs and are essential for supporting body weight and facilitating movement, particularly in the arms and legs. While it is true that long bones can contribute to some aspects of protecting vital organs and involvement in the production of blood cells within bone marrow, these are not their main functions. The primary role is to provide support and facilitate movement, making long bones critical for the body's overall framework.
