Detailed explanation-1: -Air enters the body via the nostrils or mouth. Air then travels down the throat via the larynx and trachea. Air goes into the lungs via the main-stem bronchi. One main-stem bronchus ends in the left lung and one in the right lung.
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 travels through the bronchi from the trachea, and then to the bronchioles and then eventually reaches the alveoli for exchange of gases with blood. The respiratory route of air in the respiratory tract is: Nostrils → nasal cavity →Pharynx → Larynx →Trachea → Bronchi → Bronchioles → Alveoli or air sacs.
