What is posterior segment lung?
The left lower lobe posterior or posterior basal segment is one of the four bronchopulmonary segments of the left lower lobe. It is the most inferoposterior of the segments in the left lower lobe, below the superior segment.
Which are segments of upper lobe of right lung?
Inside the right upper lobe, the right superior lobar bronchus divides into three tertiary bronchi, which provide air to the three bronchopulmonary segments: apical, anterior, and posterior. The apical segment includes the tissue of the apex and extends medially to the root of the lung.
What does right upper lobe mean?
The right upper lobe (RUL) is one of three lobes in the right lung. It is separated from the right lower lobe by the oblique fissure and the middle lobe by the horizontal fissure and subdivided into three bronchopulmonary segments.
What is the upper lobe of the lungs?
The superior lobes of each lung are the uppermost pieces, also called the upper lobes. Each lobe receives air from its own branch of the bronchial tree, called lobar (or secondary) bronchi. Within the lungs, these bronchi are divided into smaller tubes. The smallest of these tubes is called a bronchiole.
What is upper lobe posterior segment?
The right upper lobe posterior segment is one of the three bronchopulmonary segments of the right upper lobe. It is the most posterior of the segments in the right upper lobe lying below the apical segment, posterior to the anterior segment and above the horizontal fissure.
What are lung segments?
In general, each lung has 10 segments: the upper lobes contain 3 segments, the middle lobe / lingula 2 and the lower lobes 5. Bilaterally, the upper lobes have apical, posterior and anterior segments and the lower lobes superior (apical) and 4 basal segments (anterior, medial, posterior and lateral).
Where is the posterior right upper lobe?
What are the symptoms of lobar pneumonia?
Lobar pneumonia may present with a productive cough, dyspnea, pyrexia/fevers, rigours, malaise, pleuritic pain, and occasionally hemoptysis. Key features on physical examination are dullness to percussion in a lobar pattern, bronchial breathing, and adventitious breath sounds.
Where is the posterior lung?
The posterior border is thick and extends from the C7 to the T10 vertebra, which is also from the apex of the lung to the inferior border. The three surfaces of the lung include the costal, medial, and diaphragmatic surfaces. The costal surface is covered by the costal pleura and is along the sternum and ribs.
What is posterior basal segment?
The right lower lobe posterior or posterior basal segment is one of the five bronchopulmonary segments of the right lower lobe. It is the most inferoposterior of the segments in the right lower lobe, below the superior segment.
What do lung lobes do?
Each lobe of the lung has the same physiologic function, bringing oxygen into the bloodstream and removing carbon dioxide. Sections of a lobe, or even entire lobes can be removed as a treatment for conditions such as lung cancer, tuberculosis, and emphysema.
