Verified step by step guidance
1
Step 1: Begin by understanding the function of insulin. Insulin is a hormone that regulates blood sugar levels by facilitating the uptake of glucose into cells.
Step 2: Recall which gland in the human body is responsible for producing and secreting insulin. Insulin is secreted by specialized cells called beta cells located in the Islets of Langerhans.
Step 3: Identify the gland that contains the Islets of Langerhans. This gland is the pancreas, which is located behind the stomach and plays a key role in both endocrine and digestive functions.
Step 4: Compare the pancreas with the other glands listed in the options: Pituitary gland, Adrenal gland, and Thyroid gland. None of these glands are involved in insulin secretion; they have distinct roles in hormone production and regulation.
Step 5: Conclude that the correct answer is the pancreas, as it is the gland responsible for secreting insulin to regulate blood sugar levels.
