== Bursa of Fabricius ==

The '''Bursa of Fabricius''' (pronounced: bur-suh of fab-rih-see-us) is an important organ found in birds, specifically in the avian species. It plays a crucial role in the immune system of birds.

=== Etymology ===

The Bursa of Fabricius is named after the Italian anatomist, [[Hieronymus Fabricius]], who discovered it. The term 'bursa' is derived from the Latin word for 'purse', which describes the shape of the organ.

=== Function ===

The Bursa of Fabricius is responsible for the production and maturation of [[B cells]], a type of white blood cell. These cells are a vital part of the immune system, as they produce antibodies that are used to attack invading bacteria, viruses, and other pathogens.

=== Location ===

The Bursa of Fabricius is located near the [[Cloaca]] in birds, at the base of the tail. It is a sac-like organ, which is why it was named 'bursa'.
