The bronchial tree is located below the trachea and represents the airways in the lungs. The trachea divides at the level of the fourth and fifth thoracic vertebrae into the two main bronchi (bronchi principales). Due to the structure of the lung into two lobes, a distinction is made between the right and left bronchial tree. The trunk of each bronchial tree is the main bronchus and divides further into a widely branched system of tubes. In the process, the diameter of the bronchi becomes smaller and smaller and is only less than 1 mm in the bronchioles. In the process, the wall of the bronchi also becomes thinner and thinner and changes structurally. The bronchial tree represents the air conduction system of the lung, in that no gas exchange takes place.
