How many times do our ribs move while we breathe?

Humans have a set of 24 ribs, 12 on each side, which surrounds the chest and enables breathing. Ribs protect the heart and the lungs. The lungs inflate during breathing and the ribs move to accommodate the inflated lungs. This movement happens about five million times a year, corresponding to the number of times we breathe in a year.
