title: FEATURES OF THE MICROANATOMY OF THE UMBILICAL VEIN IN THE FETAL AND EARLY NEONATAL PERIODS OF ONTOGENESIS
abstract: Studying the microanatomy of the umbilical vein during the fetal period is important because of its critical role in providing the fetus with oxygen and nutrients necessary for normal development. Analysis of the microanatomical features of the umbilical vein allows us to identify the key mechanisms of adaptation of the vascular system to intrauterine conditions, which is important both for fundamental science and clinical practice. Data on age-related changes in the structure of the umbilical v
