Umbilical A', 'role': 'user'}, {'content': 'Answer: B \nExplanation: B i.e. Umbilical Vein - Umblical vein and pulmonary veins carry oxygenated bloodQ. Whereas umbilical and pulmonary aeries carry deoxygenated bloodQ. - Deoxygenated blood (with 62% 02 saturation) leave umbilical aeries to be oxygenated at placenta whereas, umbilical veins carry oxygenated blood from the placenta with Hb02 saturation of - 80% (as compared to 98% saturation in adults aerial circulation). - Right ventricle pump deoxygenated blood through pulmonary aery into pulmonary capillaries where it is oxygenated. And then oxygenated blood is carried through pulmonary veins to left atrium.', 'role': 'assistant'}]
