Bronchioles:
Each bronchus divides into smaller and smaller tubes called bronchioles.

Alveoli:
Bronchioles lead to tiny sacs called alveoli that fill up with air when you breathe. Oxygen from the air passes through the walls of the alveoli into capillaries while carbon dioxide is expelled out to the whole body.

Diaphragm:
The diaphragm is a dome-shaped muscle. The main function of the respiratory system, breathing, is started when the diaphragm contracts (when you breathe in).
