Abstract
This article deals with the research of indoos spleen macroand micromorphology. The basic anatomical features of the organ, such as size, mass, shape, color, are described. A microscopic evaluation of the splenic tissue, including the capsule, and the vascular system were conducted. The absolute mass of the spleen is found to be 0.92±0.11 g in ducks, 1.73±0.16 g in drakes, and relative 0.035 and 0.040 %. The organ is located in close to the liver between the glandular and muscle stomachs. The length of the spleen is 21±1.04 mm, width 11±0.25, thickness 6±0.01, spleen 30±0.59, width 13±0.39, thickness 8±3.07. Its parietal surface is oriented to the abdominal wall and the visceral is attached to the muscular stomach. The dorsal end is pointed and the ventral end is rounded. The caudal edge is convex and rounded, and the cranial edge is almost flat. Microstructure of the longitudinal and transverse spleen histosis shows a well-defined capsule (35±3.30 μm), clear separation into red and white pulp (relative area of white pulp – 68 %, red – 32 %), trabecular and pulsar arteries presence and markedly pronounced the lymph node zones B and T. The obtained data can be used to further study the functional features of indoos spleen and its role in the body of birds.
