Question

1. In childhood accidents with Broncho aspiration of foreign bodies occur with relative frequency, preferably located in the right bronchial tree.

a. What morphological characteristics explain that this fact is not accidental?

b. Name two anatomical relationships of the main bronchi.

c. What is the structure of the airways preceding in descending order of the main bronchi? From this structure say: extension, portions and three anatomical relationships of each portion.

Answer 1

a. As the right bronchus is more vertical and more in line with trachea compared to left bronchus. Hence chilood accident with Broncho aspiration of foreign bodies occur with relative frequency, preferably located in the right bronchial tree.

b. Anatomical relationship of Main bronchi -

- Left main bronchus :::

Posterior-esophagus, the thoracic duct, and the descending aorta

Above and front - pulmonary artery

c. Structure of the airway

Trachea --> Left and Right primary Beonchus --> Secondary bronchus --> tertiary bronchi --> Bronchiole --> terminal Bronchiole --> Respiratory Bronchiole --> Alveolar sac with lobules.
