Detailed Solution

Beyond its primary protective role for heart and lungs, the rib cage also: 

(a) serves as an anchor for respiratory muscles (intercostals, diaphragm attachment) hence assists ventilation 

(b) provides structural support for the upper trunk and shoulder girdle

(c) aids in posture and allowing movement of upper body

(d) acts as reservoir for minerals (bones store calcium and phosphorus) and blood cell production within marrow of ribs

(e) assists in transmitting forces from upper limbs to vertebral column and pelvis.
