The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks which endocrine gland decreases in size as a person ages. 2. **Identifying the Glands**: The options provided are: - Thyroid - Adrenal - Thymus - Pituitary 3. **Analyzing Each Gland**: - **Thyroid Gland**: This gland regulates metabolism and does not significantly decrease in size with age. - **Adrenal Gland**: This gland produces hormones like adrenaline and cortisol, and while it may undergo some changes, it does not significantly decrease in size. - **Pituitary Gland**: This gland is responsible for hormone regulation but does not show a marked decrease in size with age. - **Thymus Gland**: This gland is primarily involved in the immune system, particularly in the maturation of T-lymphocytes. 4. **Focusing on the Thymus Gland**: The thymus gland is known to start degenerating after puberty and continues to decrease in size as a person ages. This degeneration leads to a reduced production of thymosine, a hormone crucial for T-lymphocyte differentiation and immune response. 5. **Conclusion**: Based on the analysis, the gland that decreases in size with increasing age is the **Thymus Gland**. ---
