right and left umbilical arteries carry oxygenated blood. left umbilical vein carries oxygenated blood to the fetus. both these vessels are present in the umbilical cord.
This is to facilitate the exchange of materials between foetus and placenta.
It carries carbon dioxide and waste-laden blood from the fetus to the mother through the placenta.

The arteries
umbilical arteries
the pulmonary artery, coronary arteries and veins, inferior vena cava, branch arteries, and superior vena cava
carries blood to heart tissue riched with O2
it has two arteries along with a single vein
umbilical cord contains two arteries and one vein. umbilican vein carries pure blood to the fetal heart and umbilical arteries carry impure blood to the placenta of the mother.
The dye is injected to colour the arteries red and the veins blue. this helps in their identification.

The pathway of metabolic waste from the aorta to the outside of the body of a fetal pig begins in the aorta. The abdominal aorta, renal arteries, and bladder excrete the waste to the outside of the fetal body.
1) Arteries carry blood away from the heart while veins carry blood to the heart. 2) Arteries have thick and muscular walls (as they have to endure higher pressure) whereas veins have thin and slightly muscular walls. 3) Arteries have no valves, while veins have valves. 4) Arteries (in the post-fetal human) carry oxygenated blood except for the pulmonary arteries. Veins (in the post-fetal human) carry de-oxygenated blood except for the pulmonary veins.
A fetal chick grows into a chicken, whereas a fetal human grows into a human.
