New Morphological Ideas of the Participation of the Thymus Gland in the Processes of Immunity

Abstract

The thymus (thymus gland) is the central organ of T-lymphocytopoesis, the formation of T-lymphocyte progenitor cells and a number of thymic hormones takes place in it. Structural and functional rearrangements of the thymus under the influence of the temperature factor are characterized by cyclicity, where periods of early changes, peak and distant changes are distinguished. Each of the periods is characterized by its own characteristics, which determine the essence of adaptive organ rearrangements in response to temperature exposure.
