Explanation:

The thoracic cage is made up of the ribs, sternum, and thoracic vertebrae. It protects vital organs in the thoracic cavity like the heart. The intercostal muscles between the ribs and the movement of the thoracic - cage structure assist in breathing. It does not protect the intestines (which are in the abdominal cavity), support the lower limbs, support the upper limbs, or assist in digestion.
