Umbilical Vein, all other vessels have varying degrees of oxygenated and deoxygenated blood.
veins carry blood back to the heart, while arteries carry blood away/from the heart. therefore, the arteries carried the oxygen from the heart to the baby via umbilical artery, and the veins picked up waste products such as carbon dioxide and carried it back to the heart via the umbilical vein.
No, Umbilical arteries take deoxygenated blood from the fetus to the placenta, it is the umbilical vein carries the oxygenated blood from the placenta to the futus.
An artery is the vessel that carries blood away from the heart. The pulmonary artery carries only deoxygenated blood after birth.
Arteries carry oxygenated blood away from the heart. Arteries probably CAN carry deoxygenated blood if a person draws blood from a vein, then injects it into an artery. That would be very stupid though.
b. umbilical vein
Umbilical vein is saturated with oxygen and devoid of carbon bi oxide. Umbilical arteries has lost much of the oxygen and it is replaced with carbon bi oxide. Umbilical vein is full on digested food material, like amino acids, glucose, fatty acids, vitamins and minerals. Umbilical arteries has got waste products of metabolism and lost much of the food material to the fetus. The blood pressure is umbilical vein is very low. The blood pressure in the umbilical arteries is high.
Veins typically carry de-oxygenated blood towards the heart. The exception is the pulmonary artery and the umbilical artery.
The renal artery takes blood to the kidney. The renal vein takes blood away from the kidney. In the kidney, the waste product urea is filtered out of the blood. So the main difference is in the amount of urea in the blood: high in the renal artery and low in the renal vein.
The only artery that is supposed to carry deoxygenated blood is the pulmonary artery. It carried deoxygenated blood from the right ventricle to the lungs for oxygenation. Any artery can carry deoxygenated blood, so be careful how you word questions.
The umbilical cord - supplies blood and nutrition to the developing foetus. It's linked into the mother's circulatory system.
This is to facilitate the exchange of materials between foetus and placenta.
