Structurally-Morphological Development of the White Rat Thymus in Postnatal Ontogenesis

Abstract

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 examines 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 describes the external features of the thymus structure, internal structure, and cellular composition.
