Verified step by step guidance

Identify the function of thymosin: Thymosin is a hormone that plays a crucial role in the development and differentiation of T-cells, which are essential for the adaptive immune system.

Understand the role of the thymus gland: The thymus gland is primarily responsible for the maturation of T-cells. It is located in the upper anterior part of the chest, behind the sternum.

Recognize the relationship between thymosin and the thymus gland: Since thymosin is involved in T-cell development, it is logical that it is secreted by the thymus gland, which is the organ responsible for T-cell maturation.

Differentiate between the glands listed: The pituitary gland, thyroid gland, and adrenal gland have different primary functions and do not secrete thymosin. The pituitary gland regulates various endocrine functions, the thyroid gland regulates metabolism, and the adrenal gland produces stress-related hormones.

Conclude that the thymus gland is the correct answer: Based on the function of thymosin and the role of the thymus gland, it is clear that the thymus gland is the gland that secretes thymosin.
