4 Respiratory SystemBronchus-associated lymphoid tissue BALT consists of submucosal lymphoid tissue in intermediate and small airways. They are part of the diffuse mucosa-associated lymphoid tissue (MALT) also found in many other tissues. These structures are normal, but similar collections in lung alveolar tissue are ...Lung; lymphoid tissue; Respiratory SystemUCLA Histology
5 Respiratory SystemIn this image, a respiratory bronchiole (with intermittent alveoli) branches into alveolar ducts (walled by continuous alveoli). Alveolar sacs and alveoli can also be seen. UCLA Histology Collection.Lung; respiratory bronchiole; Respiratory SystemUCLA Histology
6 Respiratory SystemIn this small bronchus, the respiratory epithelium is less tall, with a thick basal lamina. The submucosa contains connective tissue, smooth muscle, and the mixed glands made up of serous and mucous components.

7 Respiratory SystemObserve the narrowing of this small bronchus (with cartilage plates) into a bronchiole, terminal bronchiole, then respiratory bronchiole (with intermittent alveoli). A branch of the pulmonary artery is also visible. UCLA Histology Collection.Lung; Respiratory SystemUCLA Histology
8 Respiratory SystemA macrophage rests on the alveolar wall. It is difficult to differentiate between type I pneumocytes and endothelial cells lining the alveolar capillaries. The type II pneumocytes, which produce surfactant, have large round nuclei with prominent nucleoli. UCLA Histology Collection.Lung; pneumocytes; Respiratory SystemUCLA Histology
9 Respiratory SystemPulmonary arteries are unusually thin-walled for an artery and usually travel with a bronchus. Here these conduits can be seen surrounded by pulmonary alveolar components. UCLA Histology Collection.Lung; Pulmonary artery; respiratory systemUCLA Histology
10 Respiratory SystemThis high power view shows the short ciliated cells and goblet cells of a small bronchus. Remember that the epithelium and basal lamina together constitute the mucosa. In the submucosa, find fibroblasts and the cigar-shaped nuclei of smooth muscle cells. UCLA Histology Collection.bronchus; LungUCLA Histology
11 Respiratory SystemA small number of alveolar macrophages is found in alveolar spaces of normal healthy lungs. They are part of the lung's defense mechanism. UCLA Histology Collection.alveolar spaces; Lung; macrophage; Respiratory SystemUCLA Histology
12 Respiratory SystemIdentify an alveolus and a small blood vessel. Macrophages are usually found resting on the thin alveolar wall. UCLA Histology Collection.Lung; Respiratory SystemUCLA Histology
