Yes goats do eat some weeds but the nutritional value of many weeds is very high. My studies of the nutritional value of thistles and blackberries (Table 1), for example, have shown that the nutritional value of these weeds can be as high or higher than the nutritional value of pasture.
The function of the umbilical vein is to deliver oxygenated blood from the placenta to the fetus. From the placenta, the umbilical vein courses through the liver via th â¦ e ductus venosus (fetal shunt), connecting then to the inferior vena cava. 11 people found this useful.
The umbilical vein is a vein present during fetal development that carries oxygenated blood from the placenta to the growing fetus.The blood pressure inside the umbilical vein is approximately 20 mmHg.losure of the umbilical vein usually occurs after the umbilical arteries have closed. This prolongs the communication between the placenta and fetal heart, allowing for a sort of autotransfusion of remaining blood from the placenta to the fetus.
