ANATOMY

Detailed explanation-1: -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-2: -The PHARYNX (throat) collects incoming air from your nose and passes it downward to your trachea (windpipe). The EPIGLOTTIS is a flap of tissue that guards the entrance to your trachea. It closes when anything is swallowed that should go into the esophagus and stomach. The LARYNX (voice box) contains your vocal cords.

Detailed explanation-3: -(WIND-pipe) The airway that leads from the larynx (voice box) to the bronchi (large airways that lead to the lungs). Also called trachea.

Detailed explanation-4: -After the air passes through trachea, it moves into arms of the upside-down “Y, ” the large airways called the left bronchus and the right bronchus.

Detailed explanation-5: -Air enters the respiratory system through the nose and mouth and passes down the throat (pharynx) and through the voice box, or larynx. The entrance to the larynx is covered by a small flap of tissue, the epiglottis, that automatically closes during swallowing, thus preventing food or drink from entering the airways.
