When you inhale air through your nose or mouth, it travels down the back of your throat (pharynx), passes through your voice box (larynx) and into your windpipe (trachea). Your trachea is divided into two air passages (bronchial tubes). One bronchial tube leads to the left lung, the other to the right lung.
Lungs are the major organ of our respiratory system, helping us obtain oxygen and get rid of carbon dioxide. Our chest cavity houses a pair of lungs which open to the external environment through the nose and mouth. A cylindrical tube, called trachea, is the main link between the lungs and the nose and mouth. When we breathe in, air travels through the trachea to our lungs. As the trachea moves down the chest, it splits into two branches called bronchus, one for each lung. Each bronchus then further subdivides into several smaller tubes called bronchioles.
