What does the bronchi look like?

The bronchi refers to the branches of the branches that are separated by the trachea, and the primary bronchus that is separated by the trachea, that is, the left and right main bronchus. The left and right bronchus branches down step by step. The total area of each of the left and right lobes is about 20% larger than the upper level. From the total trachea to the distal end, it is usually divided into 23 levels to form the bronchial tree. Therefore, the bronchi is indeed like a tree that is inverted, first a trunk, then divided into two, and then the more subtle, the last is the leaves (the leaves can be understood as alveoli).
