Verified step by step guidance

Step 1: Begin by identifying the primary function of the rib cage. The rib cage is a bony structure composed of ribs, sternum, and thoracic vertebrae, and its main role is to protect vital organs within the thoracic cavity.

Step 2: Consider the organ systems located within the thoracic cavity. These include the respiratory system (lungs and trachea), cardiovascular system (heart), and parts of the digestive system (esophagus).

Step 3: Focus on the respiratory system. The lungs, which are part of the respiratory system, are housed within the thoracic cavity and are directly protected by the rib cage. The rib cage provides structural support and shields the lungs from external trauma.

Step 4: Compare the other organ systems listed in the question. The endocrine system, digestive system, and urinary system are not primarily located within the thoracic cavity and are not the main systems protected by the rib cage.

Step 5: Conclude that the respiratory system is the correct answer, as it is the organ system primarily protected by the rib cage.
