Which function of the skeleton is primarily performed by the rib cage?

• A. Production of red blood cells
• B. Facilitation of movement
• C. Protection of vital organs
• D. Storage of minerals

Answer: (C)

Verified step by step guidance

1. Step 1: Begin by identifying the primary functions of the skeletal system. These include protection of vital organs, production of blood cells, facilitation of movement, and storage of minerals.
2. Step 2: Focus on the rib cage specifically. The rib cage is a bony structure that surrounds and protects the thoracic cavity, which houses vital organs such as the heart and lungs.
3. Step 3: Compare the listed functions to the role of the rib cage. While the skeletal system as a whole contributes to all the listed functions, the rib cage is specialized for protection due to its anatomical design.
4. Step 4: Eliminate functions that are not directly associated with the rib cage. For example, production of red blood cells occurs in the bone marrow, facilitation of movement involves joints and muscles, and storage of minerals occurs in the bones themselves but is not specific to the rib cage.
5. Step 5: Conclude that the rib cage's primary function is the protection of vital organs, as it forms a protective barrier around the heart and lungs.
