Question

This branches off at a more vertical angle?
1) Left bronchi
2) Right bronchi

Answer 1

The bronchus that branches off at a more vertical angle is 2) Right bronchi.

Step-by-step explanation:

The trachea, or windpipe, bifurcates into the left and right main bronchi, which further divide into bronchioles within the lungs. The right main bronchus (option 2) is relatively shorter, wider, and branches off at a more vertical angle compared to the left main bronchus (option 1). This anatomical difference is significant and can impact the likelihood of aspirated objects entering the bronchial tree.

Due to the more vertical orientation of the right bronchus, aspirated objects are more likely to enter the right lung. Understanding these anatomical variations is crucial in medical contexts, particularly when managing situations such as foreign body aspiration or intubation.

Option 2 is the answer.
