3. Nose → 1. Pharynx → 4. Trachea → 2. Bronchi → 5. Alveoli

Explanation:

In the respiratory system, the primary function is to obtain oxygen and eliminate carbon dioxide. The oxygen taken in are needed by the cells for proper body functioning and the carbon dioxide produced by the body cell is eliminated.

The respiratory system is made up of respiratory airways through which air passes. It leads in and out of the lungs.

The flow of air in the body begins from the nose. We breath in through the nose and the air moves to the pharynx, a passage that leads to the lungs. Food also passes through the pharynx. Then the air passes from the pharynx to the trachea. The bronchi connects to the trachea from the bottom of the trachea and it branches into secondary and tertiary bronchi. Then the air is taken in by the alveoli (tiny sacs) into the body where it is used.
