Which gland is listed as an endocrine gland?

• A. Pituitary
• B. Liver
• C. Stomach
• D. Kidney

Answer: (A)

The main idea is that endocrine glands release hormones directly into the bloodstream to regulate body processes. The pituitary gland fits this role exactly, as it produces and secretes several hormones (like growth hormone and thyroid-stimulating hormone) that control growth, metabolism, and the function of other glands. It’s often central in coordinating the endocrine system. In contrast, the liver is primarily an exocrine and metabolic organ (it makes bile and participates in many metabolic processes); the stomach mainly secretes digestive juices (gastric acid and enzymes) and has only some hormonal functions; the kidneys have important endocrine roles (such as producing erythropoietin) but are not classified as endocrine glands in the same way as a gland whose primary job is hormone secretion. So the gland that is listed as an endocrine gland is the pituitary.
