Simple, branched tubular gland
This image of the stomach shows the structure of a simple, branched tubular gland. The secretory sheet lining the surface invaginates to form a gastric pit that acts as a duct for the gland. The secretory portions of the gland branch at their junction with the gastric pit. Fundic stomach 400x
