What bone framework serves as a protective covering for the heart, lungs, and other delicate internal organs?

Sternum
Rib cage
Skull
Pelvis

The correct answer is: Rib cage

The rib cage serves as a protective framework for vital organs such as the heart and lungs. It is composed of the ribs, which are curved bones that extend from the spine around to the front of the chest, creating a bony enclosure. This structure not only protects the internal organs from injury but also plays a crucial role in the respiratory system by facilitating breathing movements as the ribs expand and contract. The sternum, while it does provide additional protection to the heart and is an important part of the rib cage, is not the only structure providing this protective function. The skull protects the brain but does not cover the heart or lungs. The pelvis primarily protects the lower abdominal organs but is not associated with the thoracic cavity where the heart and lungs reside. Thus, the rib cage is the most comprehensive answer regarding the protection of these vital organs.
