Microscopic image displaying cross-sectional anatomy of a fetal face. The composition emphasizes the nasal structures in the center, with nasal cartilage, nasal cavities and septum clearly visible. The tissue is stained with pink and white, creating contrast that highlights the cellular structure. Light is evenly distributed across the slide.

Nasal Mucosa

Micrograph of pharynx tissue section, Masson's trichrome stain. The epithelium (stratified squamous) appears red/pink with tightly packed nuclei. Underlying connective tissue is stained blue. Red-stained blood vessels are are interspersed within the blue connective tissue. The image is captured at high magnification, showing cellular details. The top right corner of the image is white with pharyngeal tissue visible.

Pharynx

Microscopic view of trachea tissue showing submucosal glands and the pseudostratified columnar epithelium with cilia. The light pink tissue reveals clusters of gland cells with darker nuclei in the bottom left, a middle layer with a pink fibrous appearance, and ciliated, columnar epithelial cells on the right side.

Trachea

A microscopic view of a bronchi airway featuring a simple columnar epithelium. The tissue is characterized by a single layer of tall, column-shaped cells with their nuclei aligned near the base. The cells line a lumen (space) within the airway. Cellular and structural details are visible due to the tissue staining in shades of pink and purple, which highlights the cell boundaries and nuclear material. Additional structure appears in upper right.

Bronchi

Histology slide of lung tissue at high magnification. The image shows alveoli (clear spaces) bounded by thin, pink-stained simple squamous epithelium. An artery is visible at the left and bronchioles are scattered within the alveolar structure. Stain is probably H&E. The composition fills the frame showing complexity.

Bronchioles

Microscopic view of lung tissue showing round alveoli, the air sacs of the lung, surrounded by capillaries and lined with simple squamous epithelium. An alveolar macrophage, a type of immune cell, is present in the lumen of one alveolus. Capillaries show single file erythrocytes scattered throughout the image.
