Final answer:
In the human body, there are typically five secondary bronchi, with three located in the right lung and two in the left lung.
Step-by-step explanation:
The human respiratory system includes a progression from the trachea to the lungs, beginning with the two primary bronchi or main bronchi (right and left bronchi). Each of these primary bronchi divides into smaller secondary bronchi. Typically, the right lung has three secondary bronchi, while the left lung has two, given the right lung is slightly larger due to the presence of the heart on the left side of the body. Therefore, in total, there are five secondary bronchi in the human body. These secondary bronchi further branch into tertiary bronchi, which then give rise to numerous bronchioles all the way to the alveoli where gas exchange occurs.
