Bronchial Tree Anatomy

Anatomy Of Bronchial Tree 

• The trachea at the level of sternal angle will divide into two primary branchi.

• Right bronchus is shorter, wider and vertical.

• Left bronchus is longer, narrower and oblique.

• Each Primary bronchus will divide into secondary bronchi which will supply each lobe of the lung.

• On the right side there are 3 secondary bronchi and on left side there  are 2 secondary bronchi.

• Each secondary bronchus will divide into teritiory bronchi which will further divide into teritiory bronchioles, alveolar ducts, alveolar sac, and finally alveoli.

• These are the functional units of lung where exchange of gases will occur.
