Histological photomicrograph of a bronchi sample, stained with hematoxylin and eosin (H&E). The image highlights a cross-section of the bronchi, revealing the simple columnar epithelium that forms the inner lining. The columnar cells appear stained purple due to hematoxylin staining of nuclei. The extracellular matrix and other cellular components are stained pink from the eosin. Large open space can be seen in upper right. The field of view is brightly lit, enhancing the visibility of cellular and structural details.
