After moistened, warmed and filtered air travels through the mouth and nasal passages.

It then passes through the trachea, and trachea is the connection between the throat and the lungs.

Trachea is divided into two bronchi, air is passes through one of them.

After passing into the many bronchioles, it finally arrives into some of the millions of tiny sacs called alveoli.

This is where gas exchange takes place – oxygen passes out of the air into the blood, and carbon dioxide passes out of the blood into the air in the alveoli.
