Stages of heart development in human embryogenesis

Abstract

The cardiovascular system is one of the key ones in ensuring the vital activity of the organism, as it is responsible for the transport of oxygen, nutrients and hormones, as well as for the excretion of metabolic products. Understanding the mechanisms of embryonic heart formation is important for the early diagnosis and prevention of congenital anomalies, which remain one of the leading causes of mortality worldwide. This makes the study of both normal and pathological heart development relevant. The aim of this study: A detailed consideration of the main stages of normal human heart development in prenatal ontogenesis with an emphasis on its formation and differentiation in the early stages, namely: features of the formation of the heart and its structures at different stages of embryonic development, the time limits of the beginning and completion of heart formation, analysis of the mechanisms of formationof cardiac septa and valves
