Students have asked these similar questions
For each umbilical vessel and the major fetal blood vessels, state whether each vessel carries oxygen-rich, oxygen-poor or mixed blood, and explain why the different oxygen levels occur in these vessels.
A blood sample taken from the umbilical cord contains high levels of oxygen and nutrients, and low levels of carbon dioxide and waste products. Is thissample from an umbilical artery or from the umbilical vein? Explain.
when the blood from the heart goes out into the rest of the body it is oxygen rich blood, however when it comes back to the superior vena cava and inferior vena cava would it be oxygenated blood or deoxygenated blood?
