Article: Mucus plugs in the ventral bronchi travel less distance than those in the dorsal bronchi: HRCT observation in third-order or smaller bronc
A productive cough means that there is mucus in the respiratory passages. This can be in the upper passages like the nose and throat or the lower passages like the trachea (windpipe), bronchi, bronchioles or lungs. Sometimes blood or fluid may be in the lungs and can be expelled with the...
From a pathological perspective, ABPA/ABPM is characterized by mucus plugs lodged within the bronchi (Fig. 6). Chest CT reveals mucus plugs in central airways such as the lobar and segmental bronchi, often accompanied by bronchiectasis.154 This suggests that mucus plugs are the primary lesions,...

Pathology: Grossly the tumors are soft, spherical, polypoid endobronchial nodules that are usually smaller than 2 cm in diameter but may range up to 7 cm. ○ They are more common lower or middle lobe lobar or segmental bronchi.19 ○ The differential diagnosis includes low-grade mucoepidermoid ...
Bronchiectasis: The permanent enlargement of the airways by many causes Bronchitis: Inflammation of the large airways of the lungs (bronchi) Bronchiolitis: Inflammation of the smaller airways of the lungs (bronchioles) Common cold: An upper respiratory infection caused by a variety of viruses ...
The reversible aspects of COPD generally describe excessive mucus production in the bronchial tree. Usually, there is a general increase in bulk (hypertrophy) of the large bronchi and chronic inflammatory changes in the small airways. Excessive amounts of mucus are found in the airways and semisol...
2,20 Mucus plugs occluding multiple bronchi may increase the risk of pneumonia and COPD exacerbations.6 Additionally, the presence of mucus plugs is associated with ventilation/perfusion mismatch, which may lead to respiratory failure, a common cause of death in COPD.21 In this study, the ...
