Oxygen enter the mouth and nose. The oxygen passes through the larynx and the trachea. Trachea has two small  tubes called  bronchi. The diaphragm is help pump carbon dioxide out of the lung pull oxygen in the lung.

 This relates to biology.  Respiratory system helps you breath. You need blood deliver oxygen to all the parts in the body.

How does the blood deliver oxygen to all the parts? Does it recycle in body? why the trachea is small.
