This image of a section from a lobe of the pancreas shows: 1) large numbers
of serous secretory units (acini), with circular nuclei and basophilic
cytoplasm and eosinophilic zymogen granules; 2) 3-4 islets of Langerhans,
with lightly stained cells; and 3) connective tissue septa (here seen
as artifactual spaces), which divide up the lobes of the gland into
lobules.
