Verified step by step guidance1
Understand the role of the pancreas in the endocrine system: The pancreas functions as both an exocrine and endocrine gland, with its endocrine part secreting hormones that regulate blood glucose levels.
Identify the hormones listed in the options and their sources: Aldosterone is secreted by the adrenal cortex; Parathyroid hormone (PTH) is secreted by the parathyroid glands; Thyroxine (T4) is secreted by the thyroid gland.
Recall that the pancreas secretes hormones involved in glucose metabolism, primarily insulin and glucagon, which help regulate blood sugar levels.
Recognize that insulin is the hormone secreted by the beta cells of the pancreatic islets (Islets of Langerhans) and functions to lower blood glucose by facilitating cellular uptake.
Conclude that among the options given, insulin is the hormone secreted by the pancreas.
