What is the movement of the diaphragm?

When you breathe in, your diaphragm contracts (tightens) and flattens, moving down towards your abdomen. This movement creates a vacuum in your chest, allowing your chest to expand (get bigger) and pull in air. When you breathe out, your diaphragm relaxes and curves back up as your lungs push the air out.
