Which of the following is NOT a function of the skeletal system?

Provides shape and structure for the body
Produces hormones for growth
Stores minerals like calcium
Makes red blood cells in the bone marrow

The correct answer is: Produces hormones for growth

The skeletal system has several essential functions that support the overall health and functionality of the body. Providing shape and structure is one of its primary roles, allowing us to maintain our form and posture. Additionally, it acts as a reservoir, storing important minerals such as calcium, which is vital for various bodily functions, including muscle contraction and nerve signaling. Another critical function of the skeletal system is the production of red blood cells, which occurs in the bone marrow, a soft tissue found within certain bones. The statement regarding the production of hormones for growth does not align with the primary functions of the skeletal system. While bones can influence body growth indirectly through the secretion of certain factors, the main responsibility for hormone production, particularly growth hormones, rests with the endocrine system. Thus, the correct choice indicates a function that the skeletal system does not perform directly.
