Which system gives the body structure, protects internal organs, and facilitates movement?

1. Skeletal system

2. Nervous system

3. Muscular system

4. Respiratory system

The correct answer is: Skeletal system

The skeletal system is vital for providing the body with its internal framework, which gives it shape and structure. This system is composed of bones, cartilage, and ligaments, all of which work together to protect internal organs such as the brain, heart, and lungs from injury. Additionally, the skeletal system plays a crucial role in facilitating movement; it acts as a supportive framework that muscles attach to, allowing for a wide range of motion. When muscles contract, they pull on the bones, enabling various physical activities like walking, running, and jumping. Thus, the functions of structure, protection, and movement are integral to the skeletal system.
