Bronchi (Gr.Bronchi 0300193 , the windpipe), the two main branches into which the trachea divides, at the upper part of the chest, in passing to the lungs. They are nearly cylindrical tubes composed of a series of cartilaginous rings, connected with each other by a strong fibro-elastic membrane and lined by a continuation of the mucous membrane of the trachea. The cartilaginous rings serve to keep the bronchi open and pervious for the passage of the air in inspiration. Immediately before entering the lungs each of the bronchi divides, the right into three branches, the left into two, corresponding with the number of lobes of the right and left lung respectively. These branches themselves afterward divide and subdivide in the interior of the- lungs, forming the "bronchial tubes," which finally convey the air to the pulmonary lobules and air vesicles.
