What is the left primary bronchus?

This being said, what's the purpose of the left bronchus and why is it important?

The bronchi are extensions of your windpipe that move air between the lungs and the bronchi. They can be thought of as gas exchange highways, where oxygen goes to the lungs and carbon dioxide leaves the lungs through them. They are part the conducting zone of our respiratory system.

What is the difference between the right and left main bronchi? The right main bronchus in humans is longer, wider and more vertically oriented than the left. The right Bronchum splits into three lobar Bronchi which supply the three right pulmonary Lobes. The left bronchus, on the other hand, is divided into two lobar and one lobar bronchi.

Then, in the same way, where is the left main bronchus?

The left main lung is more long, runs horizontally, and is approximately twice as long as that of the right. It reaches the hilum in the left lung at T6, just inferior to the Aortic Arch and anterior to both the esophagus & thoracic.

What number of primary bronchi do you have?

Each lung has as many as 30,000 tiny, interconnected bronchioles. Through alveolar conduits, they lead to the alveoli. The bronchial tree is made up of the trachea, the primary bronchi and the trachea. The alveolar ducts, alveolar sacs and the alveoli are located at the ends of the bronchial trees.
