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.
