Question
What is the rib cage? Write its importance.

Answer

Rib Cage (Thoracic cage or thoracic basket) : The basket-like structure formed by the chest bones and the sternum when combined is referred to as the rib cage. It is also known as the thoracic basket.
In humans, 12 pairs of ribs are found, among which 7 pairs are true ribs that are actually connected to the chest bones on one side and to the sternum on the other side. They assist in breathing.After these, three pairs of ribs are interconnected, known as false ribs. The last two pairs of ribs do not attach to the sternum or other ribs. Hence, these ribs are called Floating ribs.
Importance : The rib cage provides protection to the heart, major blood vessels, lungs, bronchi, the posterior part of the diaphragm, the lateral parts, and the lower surfaces.
