What is the primary function of the skeletal system?

The primary function of the skeletal system is to provide structural support and protection for the body's internal organs. The bones create a sturdy framework that bears the weight of the body and shields vital organs such as the heart, lungs, and brain from external injury. In addition to support and protection, the skeletal system plays a crucial role in movement, as bones act as levers for muscles. However, its most fundamental role is centered around safeguarding these essential organs, making the focus on protection particularly significant. While some bones are also involved in the process of hematopoiesis (producing blood cells), the main purpose of the skeletal system in the context of the question is its protective capability.
