APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -In the mediastinum, at the level of the fifth thoracic vertebra, the trachea divides into the right and left primary bronchi. The bronchi branch into smaller and smaller passageways until they terminate in tiny air sacs called alveoli.

Detailed explanation-2: -Further down, the trachea divides into two tubes (left and right) called bronchi (BRAHN-kye). The bronchi connect the trachea to the lungs.

Detailed explanation-3: -The point where the trachea divides into the bronchi is called the carina. The right main bronchus is wider, shorter than the left main bronchus, which is thinner and longer.

Detailed explanation-4: -The trachea divides into two small branches which are known as bronchi. A bronchus is a passage of airway in the respiratory system that conducts air into the lungs. The first bronchi to branch from the trachea are the right main bronchus and the left main bronchus.

Detailed explanation-5: -The right lung has three lobes and is slightly larger than the left lung, which has two lobes. The lungs are separated by the mediastinum. This area contains the heart, trachea, esophagus, and many lymph nodes.
