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.
Blood vessels in the placenta bring oxygen and nutrients to the foetus and remove waste products. The umbilical arteries (blue) bring oxygenated blood to the foetus while the umbilical vein (red) takes deoxygenated foetal blood back towards the placenta. The placenta connects the developing foetus to the wall of the motherâs uterus during pregnancy.
