Cloaca2

tissue_organ_import: 
bursa of Fabricius
Clinical description: 
On the dorsal wall of the cloaca is a diverticulum called the Bursa of Fabricius. This structure is an important lymphoid organ. The shape of the bursa varies with species. In the chicken, it is roughly pear shaped. In ducks, geese and turkeys it is more spindle shaped. The size varies with the age of the bird. It typically reaches its maximum size between 4 to 12 weeks of age, at which time it can weigh up to 4 grams. Normally, the bursa begins to involute when the bird is approximately 3 months of age. By the time the bird reaches sexual maturity, it may no longer be evident on gross examination.
