Final answer:
The skeletal system is composed of bones, cartilage, and ligaments. It provides support and shape to the body, protects internal organs, and facilitates movement.
Step-by-step explanation:
The Skeletal System
The skeletal system is composed of bones, cartilage, and ligaments. It has several functions, including:
- Support and Shape: The skeletal system provides structural support to the body and gives it shape. The bones act as a framework, providing a stable structure for the muscles, organs, and tissues to attach to.
- Protection: The skeletal system protects delicate organs such as the brain, heart, and lungs. For example, the skull protects the brain, while the ribcage protects the heart and lungs.
- Movement: The skeletal system works with the muscular system to enable movement. The bones act as levers, and the joints allow for different types of movement, such as bending, rotating, and extending.
