Morphometric Parameters of Histological Structures of the Spleen of White Rats in Postnatal Ontogenesis

This article is devoted to an urgent problem – the development of the spleen as an organ of the immune system at the stages of postnatal ontogenesis. In an experiment on 40 white mongrel male rats of 5 age groups using histological and morphometric methods followed by statistical analysis, data on the morphometric parameters of the spleen of white rats in postnatal ontogenesis are presented. It was found that the studied quantitative parameters of the white pulp of white rats undergo significant postnatal changes, expressed in different age aspects.
