Microscopic image of a section of oral mucosa. The upper portion of the image shows stratified squamous epithelium stained red-brown, forming a dense layer of polyhedral cells. Below, connective tissue appears blue-green with visible blood vessels. The image has a relatively high magnification, highlighting cellular and tissue structures. White background.
Microscopic view of keratinized simple squamous epithelial cells in oral mucosa.

Oral Cavity

Light micrograph of the esophagus in cross-section, stained with hematoxylin and eosin (H&E). The image presents the stratified squamous epithelium of the mucosa at the top, followed by the submucosa with mucous glands. Deep to this lies the muscularis propria, marked by striated muscle fibers. Adipose tissue is visible at the bottom. The stain renders cell nuclei a deep pink/purple and cytoplasm a lighter pink.
Esophagus cross-section including mucosa, submucosa, and muscularis externa.

Esophagus

Histological section of stomach mucosa stained with Hematoxylin and Eosin (H&E). Structures include columnar epithelial cells lining the surface, gastric pits and glands in the lamina propria. The image is primarily colored in shades of pink and purple, indicating cell structures and nuclei.
Stomach mucosa tissue under a microscope, stained pink. Visible cells and surface features.

Stomach

Light microscopy image of a cross-section of the jejunum. The image shows prominent villi extending upward, stained with hematoxylin and eosin (H&E), giving them a purple appearance. At the bottom is a muscular layer. The rest of the sample around the villi is a lighter pink. The backdrop is stark white.
Microscopic view of small intestine jejenum tissue showing purple-stained mucosa and circular folds.

Small Intestine

Histological section of large intestine mucosa, stained with hematoxylin and eosin (H&E). Vertical columns of crypts dominate the composition, featuring columnar epithelial cells with basal nuclei. Lamina propria with inflammatory cells is present between crypts. Image displays cellular morphology under magnification.
Microscopic view of large intestine mucosa, showing simple columnar cells with scattered mucus cells.

Large Intestine

A high-magnification light microscopy image of liver parenchyma stained with H&E. Hepatocytes form a reticular pattern. Portal triads containing small blood vessels are distributed throughout. The dominant color is pink/purple.
