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, which are a type of white blood cell important for immune response.

Recognize the location and characteristics of the thymus gland: The thymus is located in the upper anterior part of the chest, behind the sternum, and is most active during childhood and adolescence.

Differentiate between the glands listed: The thyroid gland regulates metabolism, the pituitary gland controls various hormonal functions, and the adrenal gland produces stress-related hormones. None of these are involved in T-cell maturation.

Conclude that the thymus gland is the correct answer: Given the role of thymosin in T-cell development, the thymus gland is the endocrine gland that secretes thymosin.
