Pancreas - intercalated duct (40x objective lens)

---

This image of the pancreas shows a cross sectioned intercalated duct (In), composed of a simple epithelium of cuboidal to low columnar cells. Above and to the left is a smaller intercalated duct (In) cut tangentially such that the nuclei of the epithelial cells can be seen but not the lumen. Surrounding the duct are numerous acini of basophilic exocrine secretory cells and several islands of light staining endocrine cells, the islets of Langerhans (IL). An arteriole (Ar) and a vein (V) are located in the interlobular connective tissue (CT), which forms as an expansion of the septa (Se).
