| bursa of Fabricius |
a lymphoid organ of birds that, like the thymus, develops as an epithelial outpouching of the gut but near the cloaca rather than the foregut; it atrophies at 5 or 6 months of age, persisting as a fibrous remnant in sexually mature birds; before involution it is the site of maturation of B lymphocytes (qv).
