What type of blood is carried by the umbilical arteries umbilical vein?
The umbilical vein carries oxygenated, nutrient-rich blood from the placenta to the fetus, and the umbilical arteries carry deoxygenated, nutrient-depleted blood from the fetus to the placenta (Figure 2.2).
Do arteries carry blood to the placenta?
The umbilical arteries carry deoxygenated fetal blood toward the placenta for replenishment, and the umbilical vein carries newly oxygenated and nutrient-rich blood back to the fetus.
Why does the umbilical vein carry oxygenated blood?
The umbilical vein is a vein present during fetal development that carries oxygenated blood from the placenta into the growing fetus. The umbilical vein provides convenient access to the central circulation of a neonate for restoration of blood volume and for administration of glucose and drugs.
Why does the fetal blood not mix with the mothers?
The placenta acts as an exchange surface between the mother and the fetus. Nutrients and oxygen are passed over by diffusion only. If the mother and the fetus had different blood types, they might both die if their blood mixed.

Can 2 O positive parents have AB positive baby?
Two O parents will get an O child nearly all of the time. But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is really unlikely). In fact, a child can get almost any kind of blood type if you consider the effect of mutations.
Can a person with O blood have a child with AB blood?
An AB and O couple producing an AB child cannot be explained in terms of the usual inheritance patterns. One would not expect the cord blood result to be AB when the mother is type O, however, in very rare instances, such as the cis-AB blood type, it is possible.
Can AB positive and O Positive make a baby?
Believe it or not, in this case having a blood type different from either parent is by far the most common result. In most cases, an O parent and an AB parent will have only A or B kids.
What does O positive blood mean?
Type O positive blood is given to patients more than any other blood type, which is why it’s considered the most needed blood type. 38% of the population has O positive blood, making it the most common blood type. Those with O positive blood can only receive transfusions from O positive or O negative blood types.
