Which system includes bones and joints critical for body movement?

The skeletal system is fundamentally responsible for body movement as it provides the framework that supports the body and protects vital organs. It consists of bones that serve as levers, which, in conjunction with muscles, enable movement. Joints are the connections between bones, allowing for various types of movement, such as bending, twisting, and rotating.

In addition to supporting movement, the skeletal system plays a crucial role in the production of blood cells and the storage of minerals, highlighting its importance beyond just movement. The interplay between bones and muscles, along with the joints that allow flexibility and motion, underscores the skeletal system's key role in facilitating physical activity and functional mobility.

Other systems mentioned, like the muscular system, are essential for movement as well, but they rely upon the skeletal system to provide the necessary support and connection points for the muscles to exert force and create movement. Thus, while all body systems work together for overall function, the skeletal system is specifically vital for the structural and mechanical aspects of body movement.
