Function of Thymus Gland
The diagram of thymus glands shows its structure which helps us learn about its various function. Some of these functions are given below:
- T cell maturation: The thymus gland is the primary site for the maturation of T lymphocytes (T cells), which are essential for adaptive immunity.
- Positive selection: Thymic epithelial cells (TECs) present self-major histocompatibility complex (MHC) molecules to developing T cells, promoting the survival of those capable of recognizing self-antigens.
- Negative selection: Thymocytes that strongly bind to self-antigens undergo apoptosis, preventing the development of self-reactive T cells and ensuring self-tolerance.
- Hormone secretion: The thymus secretes hormones such as thymosin, thymulin, and thymopoietin, which support T cell development and immune function.
- Immune surveillance: Mature T cells produced in the thymus migrate to various lymphoid organs and tissues, where they contribute to immune surveillance and defense against pathogens.
- Involution: After puberty, the thymus gradually decreases in size and activity, but it continues to play a role in immune function throughout life.
Diagram of Thymus Gland
The diagram of thymus gland shows its location in the chest and demonstrates its lobular structure consisting of cortex and medulla regions. The thymus gland is a crucial organ of the immune system. The simple thymus gland diagram shows how it plays a central role in T-cell maturation and secretes hormones supporting immune function.
