Structure of the trachea
The trachea is lined by cartilage and divided into two branches. These two branches are called the bronchi. The left bronchus enters the left lung and the right bronchus enters the right lung. Each bronchus is further divided into around 25 smaller branches. These smaller divisions of bronchi are known as the bronchioles. The bronchioles carry air into the alveoli.

The trachea is also known as the windpipe. It allows air to go from outside the body to the lungs, and back out again. It is made from rings of cartilage that are about an inch wide in diameter.
