Abstract

The present investigation aims at studying the blood flow in the umbilical vein in the first half of normal pregnancy. It was shown that the establishing of hemocirculation passes through 4 periods: 8- 10th, 11-12th, 13-16th and after the 16th week of pregnancy. Besides that, statistically verified changes in maximum blood flow speed and index of pulsation in this vessel were revealed. Constant bloodstream spectrum reflects stability of oxygenic bloodsupply of the fetus.

Keywords
