The trachea divides into two bronchi when it enters the lungs.

The trachea and bronchi share many structural components, including smooth muscle, cartilage, and cilia. However, the bronchi are only about #1.2# centimetres in diameter, whereas the trachea is approximately #1.8#.

The air passes from the trachea into the bronchi. Then, the bronchi subdivide into a massive network of smaller airways called bronchioles, which carry the blood to the alveoli, where gas exchange occurs.
