On comparing the left and right main bronchi which of the following observations are true?1
the left main bronchus is more vertical than the right one2
he right main bronchus is larger (wider) than the left one3

Concerning the Tracheobronchial tree1 a bronchopulmonary segment refers to a portion of lung supplied by a
segmental bronchus and accompanying segmental branch of the pulmonary artery
2 the upper lobe bronchus of the right lung gives rise to four segmental bronchi
3 the lower lobe bronchus of the left lung gives rise to three segmental bronchi
4 the lower lobe bronchus of the right lung gives rise to five segmental bronchi
5 in the recumbent individual the most dependent bronchopulmonary segment is the apical segment of the upper lobe
![Page 19: Questions Tracheobronchial Tree](https://reader035.vdocuments.us/reader035/viewer/2022070522/58edea671a28abe83d8b45e5/html5/thumbnails/19.jpg)

Concerning the Trachea1 the trachea divides into right and left main bronchi at the level of the
xiphisternal junction2 the trachea is separated from the upper four thoracic vertebral bodies

nerve4 the commencement of the trachea is at the level of the sixth cervical
vertebra5 the trachea has an inner lining of respiratory epithelium
