In the umbilical cord you have one vein and two arteries. This vein goes to the liver of foetus. This blood vessel contains most oxygen and food in case of foetus. After birth this vessel gets obliterated to form the falciform ligament.

How does fetal hemoglobin enhance oxygen transfer across the placenta from mother to fetus?
I'm not quite sure how it would ENHANCE oxygen transfer, but hemoglobin itself is what is in blood and is responsible for the carrying of oxygen to different parts of the body. So the hemoglobin in a fetus would just be what is used to get the oxygen from the mothers blood into its blood.
When the lungs do not function in a fetal pig what takes over their function?
The placenta. Deoxygenated blood flows to the placenta where the carbon dioxide is removed and oxygen added. Oxygen rich blood returns to the fetus. Blood is carried to and from the fetus by the umbilical cord.
What maternal conditions that interrupt oxygen flow can cause mental retardation in the fetus?
When the mother has high blood pressure (hypertension ) or blood poisoning (toxemia), the flow of oxygen to the fetus may be reduced, causing brain damage and mental retardation.
Which vessel removes urine from the bladder in the fetus?
The umbilical vessel removes urine from the bladder of the fetus via the kidneys. The umbilical vessel has many uses in the fetal/placental environment.
How does a foetus get its oxygen?
It comes from a temporary organ called the placenta. The fetus is connected to the placenta by the umbilical cord. From the placenta, which is normally attached to the uterine wall, blood, oxygen, and nutrients are transferred through the umbilical cord to the developing fetus.
Vessel with the highest oxygen concentration fetus or Adult?
Pulmonary vein
How is the circulation of a different from the circulation of a baby?
in a fetus blood does not reach the lungs for purification. In a baby blood goes to the lungs for oxygenation.
How does the fetus get its oxygen?
From the mother's blood via the placenta.
How does the fetus obtain food and oxygen?
The mother's blood supply enters the foetus via the umbillical cord and allows oxygen to diffuse from the mother's blood into the foetus.
How does a developing baby get food and oxygen during the pregnancy?
Baby gets food and oxygen through the umbilical cord. This umbilical cord is attached to the placenta. This placenta is attached to the uterus. In the placenta blood of the mother comes close to the blood of the fetus. There is transfer of food and oxygen to the blood of fetus from the blood of mother. Carbon bi oxide and waste products of metabolism are transferred to the blood of mother from the blood of fetus.
What materials would the blood arteries carry away from a fetus?
Oxygen

Why is it unnecessary for all of the blood to enter the lungs in a fetus?
It has to get oxygen and get rid of CO2
In the fetus only a small amount of blood travels from the heart to the lungs and back Why is it not necessary to send all the blood to the lungs?
a fetus doesnt require much oxygen in the lungs as it isn't in the air and isn't being breathed in. a fetus aquires oxygen through other processes
Why is is not necessary for large quantitites of blood to enter the pulminonary system of a fetus?
Oxygen is supplied by the mother since the fetus has no air to breathe.
What maternal conditions that interrupt oxygen flow can cause mental retardation in the fetus?
When the mother has high blood pressure (hypertension ) or blood poisoning (toxemia), the flow of oxygen to the fetus may be reduced, causing brain damage and mental retardation.
