Answer:
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.

Answer:
Since the diaphragm separates the chest cavity from the abdominal area, when there is a hole, or hernia, present the abdominal organs may invade the chest cavity, interfering with breathing and normal lung development.
