Verified step by step guidance

Understand the role of insulin: Insulin is a hormone responsible for regulating blood glucose levels by facilitating the uptake of glucose into cells.

Identify the organ responsible for insulin production: The pancreas is the anatomical structure that contains specialized cells called beta cells within the islets of Langerhans, which produce and release insulin.

Differentiate the pancreas from other glands: The thyroid gland produces thyroid hormones (e.g., thyroxine), the pituitary gland produces various regulatory hormones (e.g., growth hormone), and the adrenal gland produces hormones like cortisol and adrenaline. None of these produce insulin.

Recognize the pancreas as both an endocrine and exocrine organ: The pancreas has dual functions, releasing insulin into the bloodstream (endocrine function) and producing digestive enzymes (exocrine function).

Conclude that the pancreas is the correct answer based on its specific role in insulin production and release.
