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.
Air enters the body through the nose or mouth, passes through the larynx, down the trachea, and into our lungs. Once it is in your lungs, air goes through a maze of smaller and smaller bronchial tubes until it reaches clusters of tiny sacs the alveoli.In appearance they are somewhat like bunches of grapes.he alveoli are the primary gas exchange units of the lung. Quite simply, they are the point where the gas-blood barrier is thin enough to permit rapid gas exchange.
