What is the primary function of the skeletal system?

The primary function of the skeletal system is to provide support and protection to the body. The bones serve as a structural framework that not only supports the body’s shape but also protects vital organs, such as the brain, heart, and lungs, from injury. Additionally, the skeletal system plays a critical role in allowing movement by serving as points of attachment for muscles, facilitating leverage when muscles contract.

While producing hormones, providing energy for movement, and regulating body temperature are all essential functions in the body, these processes are not the primary roles of the skeletal system. For example, hormone production is primarily the role of endocrine glands, energy for movement is derived from metabolic processes, and body temperature regulation is mainly managed by the integumentary system and the circulatory system. By focusing on support and protection, it becomes evident why this function is central to the skeletal system's purpose in maintaining overall body integrity and function.
