The thoracic cavity contains the heart and lungs, both of which are constantly expanding and contracting. The ribs in the thoracic cavity serve both as protection and support, allowing the lungs to expand and contract without running the risk of putting itself into a dangerous situation, including even external threats (or more likely itself).
The abdominal contents, opposingly, are more muscular and less prone to damage, and do not need such excessive protection. Moreover, other areas such as the brain are encased in a cranial cavity of bone, and like the thoracic cavity, the organs enclosed are quite fragile. The abdominal cavity, also, contains the stomach, which may expand, which is impossible when a layer of bone is surrounding it, as is expelling it's wastes into the pelvic cavity.
