Light micrograph of a section of the lining of the human stomach, showing bleeding from a gastric ulcer. There is a profusion of red blood cells in the interior, or lumen, of the stomach at the top of the image. The micrograph shows destruction of the stomach lining, the gastric mucosa. The green- stained mucous-secreting cells and the sides of the gastric glands appear intact on the far right of the image; at left, however, the lining appears contorted & degenerated. Gastric ulcers result from an acid attack on tissue that becomes unprotected by the mucosa. Acute cases show erosion of the stomach's muscle wall and its arteries. Magnification x100 at 6x7cm size.
