english: So you use the intercostal muscles, the muscles between your ribs, to bring air in and out of your lungs just by expanding and contracting your ribcage, and if I was to put a strap  around the outside of your chest called a breath belt, and just look  at that movement, you see a rather gentle sinusoidal movement, so that's breathing.
non_english: Čiže používate vaše medzirebrové svaly, aby ste dostali vzdych do pľúc a von, len roztiahnutím a stiahnutím  hrudného koša, a keby som vám dala pás okolo vašej hrude, nazývaný pás monitorovania dýchania, uvidíte ten pohyb, vidíte celkom miernu sínusoidu pohybu, to je dýchanie.
