MORPHOLOGICAL CHANGES IN LUNG TISSUE AND SMALL CALIBER ARTERIAL BLOOD VESSELS DURING COVID-19 INFECTION

Abstract

In the period after the Covid-19 pandemic, SARS-CoV-2 caused a nonspecific response of most organs and tissues of the pathogen. In particular, blocking of the APF-2 receptor in the blood vessels of the lung tissue caused the development of acute dystrophic and necrotic changes in the form of respiratory distress syndrome, derailing the principle of nutrition of the vessels in the organs. Specific principles of morphological changes in blood vessels of lung tissue were studied in autopsies of those who died with the diagnosis of Kovid-19. Changes in the endothelial area of the components that make up the vessel wall were studied. During the studies, it was found that thrombi develop as a result of acute swelling and desquamation of endotheliocytes
