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.
Circulation to the placenta then ceasesâthe arteries close first to prevent blood leaving your babyâs body. The umbilical vein continues to provide oxygenated blood to your newborn for an average of 15 minutes (unless it is clamped and cut sooner). The umbilical cord will pulse until the process is complete.
