Arteries have a smaller lumen (centre passage) than veins do, they also have thicker more 'muscular' walls than veins do. This is because blood pressure is higher in arteries than in veins, as arteries carry blood away from the heart, veins carry blood to the heart, pressure has to be high in arteries so that blood can reach all around the body.
the umbilical artery the umbilical artery
The umbilical artery forms the superior vesicle arteries and in males it becomes the artery to the ductus deferens in the penis.The right umbilical vein degenerates and the left becomes the ligamentum teres around the liver.
yes
Umbilical Vein, all other vessels have varying degrees of oxygenated and deoxygenated blood.
The nature of an artery in the umbilical cord is to take waste products from the baby. It is then sent back to the placenta by two veins.
b. umbilical vein
congenital renal artery stenosis
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.
This is normal.
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.
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.
An artery is the vessel that carries blood away from the heart. The pulmonary artery carries only deoxygenated blood after birth.
