The aim of the article is to analysis of the hemodynamic parameters of the uterus and cervix during the second and third trimesters of pregnancy. Material and methods. It was conducted dynamic ultrasound in 240 women with physiological course for singleton pregnancies in the period from 12 weeks of gestation until term labor. Results. For the second trimester of pregnancy redistribution of total uterine blood flow in the direction of increasing blood flow in more of the body than the cervix has been considered to be typical. From the third trimester of pregnancy until term labor a significant increase of blood supply to the cervix has been found; there has been a tendency to increase the capacity of the vascular channel and the reduction in peripheral resistance vessels of cervix. Conclusions. Early detection of disorders of uterine and cervical hemodynamics allows to predict the occurrence of various pathological conditions.

The review considers the current understanding of mechanisms that regulate uterine contractions and the nemo-dynamic changes in the cervix uteri occurring prior to and during delivery. Disorders in hemodynamic transformation of cervix uteri are the most significant causes of delivery anomalies. The criteria for ultrasound diagnostics of the degree of maturity of cervix uteri have been analyzed. Cervix blood flow parameters have been taken into account. The further research perspectives in this field of scientific problems have been stated
