Which tissue type is identified in the image?

• A. Pancreas
• B. Lung
• C. Kidney
• D. Heart

Answer: (A)

Pancreatic tissue is recognizable by its two distinct components: dense exocrine acini and scattered lighter-islet clusters. In the image, the acinar cells form lobules with tightly packed, basophilic cells and visible ducts weaving between them. The pale, rounded clusters are the islets of Langerhans, which stain lighter compared with the surrounding exocrine tissue. This combination—organized acini with ducts plus isolated islets—is characteristic of the pancreas and helps distinguish it from the other organs shown. The lung would show alveolar air spaces and bronchial structures, the kidney would display glomeruli and tubular epithelium, and the heart would reveal striated cardiac muscle with intercalated discs.
