Bronchi: Anatomy, function and histology - Kenhub
2023年10月30日 · Every generation, starting from primary, is supported by cartilage in its wall. After the sixth generation, the passageways are too narrow to be supported by the cartillage, and thus are called bronchioles (small bronchi). This article will discuss the anatomy of the bronchi.

Respiratory: The Histology Guide - University of Leeds
Small sacs are found extending from the walls of the terminal bronchii called respiratory bronchioles (R), that are lined by a ciliated cuboidal epithelium, and some non-ciliated cells called clara cells. Click here to find out more about the respiratory portion of the lung.

2023年5月1日 · The bronchi begin as a branching pattern, splitting next into lobar (secondary) bronchial branches and then again into segmental (tertiary) bronchi. The tertiary bronchi continue to divide into small bronchioles where the first change in histology takes place as cartilage is no longer present in the bronchioles.

These bronchioles with alveoli in their walls are called respiratory bronchioles [example] . They characteristically exhibit a progressive reduction in height of the epithelium and in the amount of smooth muscle between the openings of adjacent alveoli.

Consult your histology textbook and/or atlas (e.g., Rhodin, figures 31-35 to 31-40) for additional detail and electron micrographs of bronchial and bronchiolar cells. Small mucous glands are scattered along most of the respiratory tree and may occasionally be …
Lower respiratory tract: Histology and function - Kenhub
2023年10月30日 · After about 10 – 15 cm, the trachea bifurcates at the carina to form a left and a right primary bronchus. The bronchi are also kept patent by C-shaped rings of hyaline cartilage and their lumens are also lined with respiratory epithelium. The primary bronchi enter the lungs and further divide into secondary (intrapulmonary) bronchi.

Venules collect capillary blood into lobular septa, forming veins and joining at the hilum. Gross bronchi, filled with mucus or pus, lower lobes. Bronchospasm, usually reversible, due to allergic or non-allergic stimuli. Anatomic targets -bronchial epithelium and smooth muscle.
