When we breathe out, the muscles between the ribs move down and
inwards. The diaphragm moves upwards. The volume inside the chest decreases. This causes air to rush out of your lungs.
P.S. I copied that out of my science work sheet. LOL!
The diaphragm goes down, pulling air into the lungs. Your ribs expand, helping your lungs to expand also.
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 name of the muscle that is attached to your ribs is called a Diaphragm,it helps your lungs to breathe.
The ribs don't do anything when you breathe it's your diaphragm that makes you 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
rib could be out.
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.
the ribs expand slightly to give the lungs room to expand also.
