How is our chest able to expand and contract?

When we breath in our chest expands to some extent but I don’t understand how it that possible. Bones can’t expand or anything, so how are we able to “expand them”, make them “longer”?

Everything to some degree has elasticity or stretchitude Some things more than others. Flesh and other meaty human bits have a good bit of it. As temperature and pressure cause things inside you to expand and contrast muscles and all of their neighbors who live inside you put force on your interior causing expansion and decompression. You have to be careful though because things that stretch do have breaking points. Just don’t go too far down the human inflation rabbit hole unless you are ready to see some things they don’t teach in health class, but hey we don’t kink shame here.
