The air is:
- heated (to body temperature)
- cleansed (foreign particles attach to the mucosa of the nasal cavity and thusly removed before they reach the lungs).
- moistened (the humidity of the air increases)
All of these mechanism are designed to help the lungs to a better supply of air.
True Mucus helps moisten warm and filter the air as it enters the nose.

The upper respiratory system (where air enters and exits the body) is composed of the nasal cavity, pharynx, and larynx. The lower respiratory system (where the air moves to be processed) consists of the trachea, the bronchi, and the lungs. So the answer is either the nose and mouth, or the trachea, depending on how you meant the question.
It starts in the nose/mouth, then the air enters the lungs. It then goes into the bronchi ole into the air sac. It is then transported to the circulatory system to produce waste. There is another way which is that the nose/mouth inhales air then it travels down the trachea into the lungs where the waste is produced it then goes to the bronchi then into the circulatory system.
The turbinates at the top of the nose are moist and exist to moisten air as it enters the respiratory tract.
Through your nose and mouth.
Air enters the the respiratory tract through either the nose or mouth.

As the diaphragm contracts, air enters the body through the nose and mouth.

The mouth and the nose is where air comes in.
Air enters through your nose or mouth to your air sacs.
Yes, both the mouth and nose help to moisten and warm air before it enters your lungs.

Two air passages which allow air to enter the body are the cilia and aveoli !!!
