MORPHOFUNCTION DEVELOPMENT OF THE WHITE RAT THYMUS IN POSTNATAL ONTOGENESIS

The thymus is the central or primary organ of the lymphoid (immune) system. Its main functions are to ensure the maturation and differentiation of thymocytes, the integration of various populations of thymocytes and macrophages for the implementation of immune responses. The article studies and presents the latest scientific data on the development of the thymus, its structure and cellular composition. Both well-known sources and new literature were used. This article shows the external features of the structure of the thymus, the internal structure, as well as the cellular composition.
