The development of venous circulation in fetoplacental system is one of the least known problems in perinatology. In work by a method of ultrasonic Doppler is investigated the development of blood flow in umbilical vein, v. cava inferior and jugulaar veins of a fetus with 8-th on 40-th week of normally developing pregnancy. It is shown, that the parameters of blood flow in the given vessels depends on gestational age of a fetus, conditions of venous return to heart and functional importance of venous vessel.
