Into how many bronchi does the trachea branch?

The trachea branches into two primary bronchi, which is why the correct answer is two. Each primary bronchus leads to a lung, with the right primary bronchus being wider and more vertically oriented than the left. This branching structure is crucial for directing air into each lung, allowing for efficient gas exchange. After entering the lungs, each primary bronchus further divides into secondary (lobar) bronchi and then into tertiary (segmental) bronchi, but the initial branching from the trachea is specifically into two primary bronchi. This anatomical arrangement supports the need for each lung to receive adequate airflow, facilitating the respiratory process.
