Quizplus · Accepted Answer

The first branch from the trachea is called the primary bronchus, which leads to the right and left lungs. This eventually branches into smaller bronchi, known as secondary and tertiary bronchi, before reaching the alveoli where gas exchange occurs. The hilus is a region on the surface of the lung where blood vessels and bronchi enter and exit.
