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 cord is the life-line that attaches the placenta to the fetus. The umbilical cord is made up of three blood vessels: two smaller arteries which carry blood to the placenta and a larger vein which returns blood to the fetus. It can grow to be 60 cm long, allowing the baby enough cord to safely move around without causing damage to the cord or the placenta.
