Inter-Organ Relationships of the Thymus and Spleen in the Dynamics of Temperature Exposure

Abstract

The central (thymus, bone marrow) and peripheral (spleen, mesenteric lymph
nodes) organs of the immune system in the dynamics of temperature exposure have been studied
by complex morphological methods. Separate periods of immunomorphological adaptive
rearrangements of the organs of the immune system in response to antigenic effects were
established: early changes (3-24 hours of the experiment), pronounced immunomorphological
rearrangements (from 3 to 14 days of the experiment) and reconvalescence (from 14 to 21 days of
the experiment). Each of these periods is characterized by the dynamics of morphological and
functional changes that ensure immune homeostasis in response to temperature exposure.
