What is the function of the skeletal system?

The skeletal system primarily serves the essential functions of providing structure, support, and protection for the body's organs. It is composed of bones, cartilage, and ligaments, which together form a framework that gives the body its shape and physical stability. This framework not only supports the body's overall structure but also protects vital organs; for example, the skull encases the brain, and the rib cage shields the heart and lungs. Additionally, the skeletal system plays a crucial role in facilitating movement by serving as attachment points for muscles, which contract to allow movement at joints. Other aspects of bone function include mineral storage and housing the bone marrow, where blood cells are produced.

In contrast, the other functions mentioned in different choices involve other systems: the endocrine system is responsible for hormone production, the circulatory system handles the delivery of oxygen and nutrients, and the digestive system facilitates food processing and nutrient absorption.
