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 coated in a substance called Wharton's jelly, which serves to strengthen the cord and protect the blood vessels inside. The maternal end of the umbilical cord is attached to the placenta, which acts as an intermediary between the umbilical cord and the mother's circulatory system. The other end attaches to the fetus in the abdominal area (what will later become a person's navel or belly button).
