Detailed explanation-1: -Air moves through these passages during breathing. The nasal passages filter and warm the air, and make it moist before it goes into the lungs. They also contain special cells that are involved in the sense of smell.

Detailed explanation-2: -When you inhale through your nose or mouth, air travels down your pharynx (back of your throat), passes through your larynx (voice box) and into your trachea (windpipe). Your trachea is divided into two air passages called bronchial tubes. One bronchial tube leads to your left lung, the other to your right lung.

Detailed explanation-3: -The air passing through the nostrils is filtered by the fine hairs and mucus present in nostrils.

Detailed explanation-4: -Your lungs do more than move oxygen in and carbon dioxide out of the body. They also act as filters. Mucus in your lungs catches and holds dust, germs, and other things that have entered the lungs. When you cough, sneeze, or clear your throat, you move this material out of your body.
