Which system is responsible for body movement and maintaining posture?

1. Digestive system

2. Nervous system

3. Musculoskeletal system

4. Respiratory system

The correct answer is: Musculoskeletal system

The musculoskeletal system is the correct choice because it is made up of bones, muscles, cartilage, tendons, and ligaments, all of which work together to facilitate movement and provide structure to the body. This system allows for various types of movement, from simple motions like walking to complex movements required in sports or daily activities. Additionally, it plays a crucial role in maintaining posture by supporting the skeletal structure and allowing for the necessary muscle contractions to keep the body upright and balanced. In contrast, while the nervous system is vital for coordinating movements and sending signals to the muscles, it does not directly create movement. The digestive and respiratory systems primarily focus on processes like nutrient absorption and gas exchange, which are essential for sustaining life but do not contribute to movement or posture maintenance.
