The respiratory system consists of your lungs, trachea, and oral/nasal passage. There are 2 lobes of lung tissue in your left lung and 3 lobes in the right. The bronchi are upper airway and the trachea is the a cartilaginous tube that connects the nasal and oral airway leading to your bronchi and lungs. The epiglottis is a muscular valve that allows for breathing or swallowing. When you swallow, it opens and closes to allow food to pass into your esophagus and bypass the airway.
