What is the primary function of the skeletal system?

1. Protect vital organs and support body shape

2. Regulate body temperature

3. Facilitate movement through muscle contraction

4. Produce hormones and enzymes

The correct answer is: Protect vital organs and support body shape

The primary function of the skeletal system is to protect vital organs and support body shape. The skeletal system comprises bones, cartilage, and ligaments that provide the framework for the body. This framework not only shapes and gives structure to the body but also serves as a protective barrier for essential organs. For instance, the rib cage protects the heart and lungs, while the skull protects the brain. Additionally, the skeleton supports the body's weight and enables posture, making it crucial for overall bodily function and appearance. While the skeletal system does play a role in facilitating movement through the joints and muscles working together, the primary intention of the skeletal structure itself is to offer protection and support. Regulating body temperature and producing hormones and enzymes are functions associated with other systems in the body, such as the endocrine system and the integumentary system, rather than the skeletal system itself.
