Immunity is the body’s ability to fight off foreign invaders, such as viruses and bacteria. At the heart of this important defense system are the thymus gland and T-cells, which we’ll discuss in this article, including what they are, how they function, and how they relate to T-cells.
Definition and Location of the Thymus
The thymus is a crucial organ in our immune system located in the upper chest, just behind the sternum and above the heart. It aids in the maturation and differentiation of T cells.
Form and Structure of the Thymus
The thymus has a leaf-like shape, divided into two lobes, each further divided into many lobules. These lobules contain an outer cortex and an inner medulla, where T cells mature.
Function of the Thymus
The primary function of the thymus is to produce and mature T cells, which are essential for recognizing and attacking pathogens.
Related Diseases
Diseases related to the thymus include thymoma (thymus tumor) and myasthenia gravis, an autoimmune disorder.
Thymus and T Cells
The thymus is akin to a “school” for T cells, where they learn to distinguish between self and non-self antigens before regulating immune responses throughout the body.
Roles of T Cells
T cells have two main roles: directly attacking infected or cancerous cells and regulating other immune cells’ activities.
