What is a bronchopulmonary segment?
The bronchopulmonary segment, sometimes called a tertiary bronchus, is a part of the respiratory tract that supplies oxygen to the smallest parts of the lungs where oxygen with carbon dioxide during breathing occurs. There are 18 to 20 different bronchopulmonary segments located in one set of lungs. The left lungs have upper and lower lobes, each containing four bronchopulmonary segments. There are ten bronchopulmonary segments in three right lung lobes. Each segment is able to function independently of the part next to it, allowing the removal of patient lung tissue without changing the functionality of neighboring segments. Small pieces of cartilage hyaline provide structural support for smooth muscle tissue that forms a tube. It is located in the middle space of each bronchopulmonary segment, is bronchial artery and pulmonary artery. Veins and lymphatic vessels that each of the segments give along the outer structure in the shape of the tube. Among the segments are very thin layers of connective tissue that separate the broncHU into individual sections.
Most people have eight segments in their left lungs; However, several people can have up to 10 individual segments. Four bronchopulmonary segments located in the upper lobe of the left lung are named after their location in this lobe. Excellent lingular segment and lower lingular segment are placed on top of each other. The front segment is located towards the front of the top of the left lungs. Behind the front segment is the apicoposterior bronchopulmonary segment.
under the upper left lobe of the lung is the lower lobe lobe. Towards the front and center of the lower lungs is anteromedial bronchopulmonary segment. Above the anteromedial segment is an excellent segment. The rear segment is located towards the bottom of the lungs. The lateral segment provides an air passage that travels to the outside of the left plice.
Ten bronchopulmonary segments are found in three lobesthe right lungs. The upper lobe contains apical, rear and front segments. In the middle lobe, the medium and side segment provides air to the lungs. Five bronchopulmonary segments were identified inside the lower lobe. It is known as superior, front, medium, rear and side segments of the right lung lobe.
diseases of bronchopulmonary segments can be diagnosed after chest computer tomography (CT). The segment can be identified by anatomical structures specific to bronchopulmonary segments such as segmental arteries and bronchi. Patients or incorrect bronchopulmonary segments can be surgically removed without disturbing the functionality of the remaining segments.
