Bursa of Fabricius
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'.
