Which gland secretes thyroxine?

Adrenal gland
Pituitary gland
Thyroid gland
Pancreas

The correct answer is: Thyroid gland

The thyroid gland is responsible for the secretion of thyroxine, which is a key hormone involved in regulating metabolism. Thyroxine helps control how the body uses energy, influences growth and maturation, and plays a significant role in maintaining overall metabolic processes. This hormone impacts various organ systems, facilitating efficient energy production and utilization. Other glands listed, such as the adrenal gland, the pituitary gland, and the pancreas, have distinct hormonal functions which do not encompass the production of thyroxine. The adrenal gland produces hormones like cortisol and adrenaline, the pituitary gland secretes multiple hormones that regulate other endocrine glands, and the pancreas is involved in insulin production for blood sugar regulation. Each of these organs contributes to hormonal balance in the body, but only the thyroid gland is the source of thyroxine.
