Question: 1 / 400

What is NOT a primary function of the skeletal system?

Protection of vital organs

Production of blood cells

Support for body posture

Provides protective covering on body surfaces

The skeletal system serves several essential functions, including providing protection for vital organs, producing blood cells within the bone marrow, and offering support for the body’s posture and structure. Each of these functions is vital to maintaining overall health and facilitating movement.

The protective covering on body surfaces is primarily the role of the integumentary system, which includes the skin, hair, and nails. This system protects the body from external damage, pathogens, and dehydration. Therefore, it is not the skeletal system that provides a protective covering on body surfaces, making this the correct choice for what is NOT a primary function of the skeletal system. Understanding the distinction between the functions of the skeletal system and those of other systems, such as the integumentary system, is crucial for grasping the interconnectedness of human body systems and their respective roles.
