The ribs don't move when inhaling. They may be particularly flexible and when you press on them they may bend a little before breaking. Also, the ribs are attached to the spine, so if they did move that could be particularly dangerous and even fatal. However, the only thing that flexes when breathing is the lungs.
Your diaphragm lowers and your ribs expand outwards
The diaphragm goes down, pulling air into the lungs. Your ribs expand, helping your lungs to expand also.
The ribs rise up during inhalation when the diaphragm contracts and moves downward, creating more space in the chest cavity. This causes the ribs to move up and outwards. During exhalation, the diaphragm relaxes and moves back up, while the ribs move downward and inwards to decrease the space in the chest cavity.
It contracts and relaxes to help pull air into the lungs and push it back out. The diaphragm contracts and moves lower which expands the ribs and allows air to move into the lungs. When it relaxes, the ribs contract and push air back out of the lungs.
During inhalation, the ribs move outward as the diaphragm contracts and the chest cavity expands to allow the lungs to fill with air. During exhalation, the ribs move inward as the diaphragm relaxes and the chest cavity decreases in size, forcing air out of the lungs.
only the ribs work with the respiratory system. When there is low pressure in an area air will rush to fill in the space, in high pressure however air will rush away from it. when the ribs move up and out the pressure decreases and the volume increases air will rush in your lungs (inhaling) but when the ribs move down and in it squeezes the lungs increasing the pressure and lowering the volume so air will rush out (exhaling)
Ribs
A misunderstanding. That's not how breathing actually works. Your rib cage is all but immobile.
it expands as we inhale and contrasts as we exhale...this allows our lungs to fill up with air without pushing on out rib cage the rib cage moves up and out when inhaling and moves down and in when exhaling.

i would say the spine because its involved in the movement of many of the other bones
It is air that does it, as well as the rib muscles themselves. The diaphragm contracts, expanding the internal area of the thoracic (chest) cavity, causing a drop in pressure. Air is then drawn through the nose into the lungs, which expand, causing the ribs to move to accomodate this.
