When you breathe in, the ribs expand outward and the diaphragm contracts and moves downward, creating more space in the chest cavity. This allows the lungs to fill with air and oxygen to be taken in.
Outwards and upwards
If you're relatively thin, or averagely built, breathe in and your ribs will show.
The cartilage between your ribs and breastbone allows for flexibility and movement of the ribcage during breathing. As you inhale, the cartilage expands and stretches, while it contracts and returns to its original position when you exhale. This movement helps to accommodate the expansion and contraction of the chest cavity during breathing.
The ribs don't do anything when you breathe it's your diaphragm that makes you breathe.
the name of the muscle that is attached to your ribs is called a Diaphragm,it helps your lungs to breathe.
It moves inward.your ribs will be bend out
i would say the spine because its involved in the movement of many of the other bones
Because they have to move to let your lungs expand and compress as you breathe in and out.
They should not hurt at all unless you have damaged them some way.
rib could be out.
the ribs expand slightly to give the lungs room to expand also.
