Detailed explanation-1: -The correct answer is Umbilical cord. It is a narrow tube-like structure present that connects the embryo with the placenta through the umbilical cord, which helps in the transportation of nutrients and oxygen to the fetus and also excretes out carbon dioxide and the metabolic wastes from it.
Detailed explanation-2: -The umbilical vessels carry the fetal blood back and forth to the placenta, with the umbilical vein carrying oxygenated blood with nutrients from the placenta to the fetus and the umbilical arteries transporting deoxygenated blood with waste products from the fetus to the placenta.
Detailed explanation-3: -The umbilical vein carries oxygenated, nutrient-rich blood from the placenta to the fetus, and the umbilical arteries carry deoxygenated, nutrient-depleted blood from the fetus to the placenta (Figure 2.2).
Detailed explanation-4: -The placenta is a temporary organ that begins to form from the trophoblast layer of cells shortly after implantation. It allows nutrients and wastes to be exchanged between the mother and fetus.
