What is one of the primary functions of the skeletal system?

The primary function of the skeletal system is to protect, support, and serve as attachment sites for muscles and organs. The bones create a framework that maintains the structure of the body, safeguarding vital internal organs such as the heart and lungs from injury. Additionally, the skeletal system facilitates the connection of muscles to bones through tendons, enabling movement. This supportive role is crucial for overall mobility and stability, making it essential for the functioning of the entire musculoskeletal system.

In contrast, while producing hormones is a function of certain glands and organs, it is not a primary role of the skeletal system. Creating movement in the limbs is dependent on muscle contraction, while the skeletal system provides the structure that enables this movement, so it is more of a supporting role rather than a primary function. Storing fat is a role of adipose tissue, particularly in certain bones known as yellow marrow, but it does not define the primary functions of the skeletal system.
