What are the primary functions of the skeletal system?
The primary functions of the skeletal system are:
1. Support: Provides a framework for the body, allowing us to stand upright and maintain posture.
2. Protection: Shields internal organs, such as the brain, heart, lungs, and spinal cord, from injury.
3. Movement: Acts as a system of levers and joints, allowing for movement, flexibility, and mobility.
4. Blood cell production: Bones are responsible for producing blood cells, including red blood cells, white blood cells, and platelets.
5. Storage of minerals: Bones act as a storage site for minerals like calcium and phosphorus, which are essential for various bodily functions.
6. Endocrine functions: Some bones, like the parathyroid glands in the neck, produce hormones that regulate calcium levels.
7. Stability and balance: Helps maintain balance and stability by providing a foundation for muscles to attach and pull against.
