It gives it some flexibility when the ribcage expands and contracts with pulmonary ventilation.
So your chest can expand to get air into your lungs :3
because if your joints moved a lot, your lungs would not be properly protected and you would probably end up breaking your ribs.

Ther is not one single bone that protects both organs. Your sternum protects your heart. Your ribs form a rib cage which protects your lungs.
A bony cage is a structure used to protect vital organs. There is nothing in the arms or legs that needs protection of this kind; they only consist of bone and muscle, which can handle bumps and breaks.
Large flat bone, 15-20 cm/5.9-7.8 in long in the adult, at the front of the chest, joined to the ribs. It give protection to the heart and lungs. During open-heart surgery the sternum must be split to give access to the thorax.The sternum can be felt beneath the skin throughout its whole length, from the root of the neck into the abdominal wall. It has three parts - the manubrium, body, and xiphoid process - which are united by cartilage. The joint between the manubrium and body, the sternal angle, can be felt opposite the second ribs.Hopes that this Helps :}
under the breast lies the ribcage- that little bone betwen the rib cage and protecting them is the sternum
The heart, lungs, and liver are protected by the rib cage, breast bone (sternum), and back bone. These bones provide a protective cage around these vital organs.
The ribcage is made of lots of bones and the skull is made of two bones.
The lungs fill the chest cavity with the heart resting between the lungs and slightly to the left. All of these organs are protected by thr breast bone and rib cage.

Symptoms of cholecystitis is typically steady pain in the upper right abdomen near the rib cage. Some patient experience pain from behind the breast bone.

The Rib cage is the biggest bone in your body.
Skull, collarbone(clavical), sterum(breast bone), shoulder blade, rib cage, humerus, radius and ulna(the forearm), pelvis (hip bone), pubic bone, scrotum, femur, tibia and fibula(the lower half of the leg) NOTE: Not all bones were included.
Begin by cutting from the neck to the tail along the breast bone, then angle the knife outwards along the rib cage. Slice the breast across, and repeat with the other breast. Pull the leg outwards and cut around the joint to remove it, and repeat. Find the joint between the leg and thigh bones and slice the thigh meat along the thigh bone and repeat with the other leg.
the back bone is the vertebrae
