Wall structure
The bronchi are first surrounded by cartilaginous braces. These serve to stabilize the bronchi. The shape of the cartilage braces have a horseshoe-like shape. In this case, the ends of the cartilage are connected by smooth muscles. The proportion of cartilage in the bronchioles decreases significantly during branching and that of the musculature increases. There is then no cartilage left in the bronchioles. They now consist only of smooth muscle.
