What is a primary function of the musculoskeletal system?

The primary function of the musculoskeletal system is to provide support, stability, and protection for the body, including safeguarding internal organs. This system comprises bones, muscles, and connective tissues, which together allow for movement while also creating a strong framework that shields vital organs such as the heart, lungs, and liver.

For instance, the rib cage, which is part of the skeletal component, encases and protects the heart and lungs from physical harm. Additionally, the structural integrity and strength provided by bones prevent excessive movement of organs during physical activities. This protective role is essential for maintaining the overall function and health of the body.

In contrast, the other options refer to different systems or functions in the body: providing energy falls under metabolic functions, regulating body temperature is primarily managed by the integumentary and nervous systems, and hormone secretion is primarily a function of the endocrine system. Thus, understanding the specific role of the musculoskeletal system in protecting internal organs highlights its importance in overall body function.
