The Thymus

This week's episode explores an organ that until the 1960s was thought to be vestigial. A primary lymphoid organ that is vitally important in the development and maturation of your immune system as a child. However, as an adult, it undergoes involution and appears as nothing more than some fatty tissue. An organ that is sometimes called a gland, that is not a gland but looks like a gland.....enter the Thymus.  

We will explore the location of the thymus, its anatomic features, its functions, and in doing so uncover the origins of immunity and our lymphocytes (T cells & B cells).
