The general shape of the thoracic cage is like a slightly conical cage, narrowing at the top and expanding towards the bottom to accommodate the organs in the chest. It is composed of the sternum, ribs, and thoracic vertebrae, providing protection for the heart and lungs.
As you grow, of course the chest cavity changes shape as you grow. The thoracic cavity does change shape internally, even when the rib cage does not appear to move. The thoracic diaphragm is most important in breathing, and does much of our breathing.

Yep, the ribs are what make up the thoracic cage.
The thoracic cage protects the heart and lungs, supports the shoulders and upper limbs, and plays a role in breathing by expanding and contracting during respiration. It also serves as an attachment point for muscles involved in arm movements and posture.
d. Thoracic cage
The part of the skeleton enclosing the thorax, consisting of the thoracic vertebrae, ribs, coastal cartilages, and sternum.
Ribs
no
A typical human thoracic cage consists of 24 ribs, the sternum and 12 thoracic vertebrae.
Ribcage is the scientific name.The rib cage defines the thorax, or upper body, so the medical term for rib cage is 'thoracic cage'. (Thore -ASS-ik)
When the volume of the thoracic cage decreases, the pressure inside the thoracic cavity increases. This increased pressure aids in exhalation by forcing air out of the lungs.
