Bronchi vs. Trachea

What's the Difference?

The bronchi and trachea are both important components of the respiratory system, responsible for the transportation of air to and from the lungs. The trachea, also known as the windpipe, is a long tube made of cartilage rings that connects the larynx to the bronchi. It is lined with ciliated cells and mucus-producing cells, which help to trap and remove foreign particles from the air. On the other hand, the bronchi are two main branches that extend from the trachea and enter each lung. They further divide into smaller bronchioles, which eventually lead to the alveoli where gas exchange occurs. While the trachea is a single tube, the bronchi are a pair of tubes that branch out to each lung. Both the bronchi and trachea play crucial roles in ensuring the smooth flow of air into and out of the lungs, facilitating efficient respiration.
