Which organ is identified in the image as coming from a glandular organ?

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

Answer: (A)

Pancreas is a glandular organ because its tissue is built for secretion, with distinct secretory units (acini) that produce digestive enzymes and ducts that carry those enzymes to the gut, plus endocrine islets that release hormones into the bloodstream. On histology, seeing organized clusters of acinar cells with secretory granules and ducts points to glandular pancreatic tissue. The image likely highlights this secretory organization, which is characteristic of a gland rather than a non-glandular organ. The other options don’t primarily function as secretory glands: the lung is a respiratory structure with alveoli and airways; the kidney focuses on filtration and reabsorption with tubules and glomeruli; the heart is composed of cardiac muscle tissue.
