What is the purpose of sternum and rib cage?

Sternum

- The sternum, or breastbone, is a flat bone that forms the front of the chest.

- It is composed of three parts: the manubrium, the body, and the xiphoid process.

- The sternum protects the heart, lungs, and other vital organs in the chest.

- It also provides attachment for the ribs and muscles of the chest.

Rib cage

- The rib cage is a series of 12 pairs of curved bones that form the sides and back of the chest.

- The ribs are attached to the spine at the back and to the sternum at the front.

- The rib cage protects the heart, lungs, and other vital organs in the chest.

- It also helps to support the upper body and provide mobility for breathing.

Together, the sternum and rib cage form a protective cage that surrounds and protects the vital organs in the chest.
