Question

What would occur if a fetus's chorion tissue ruptured? The maternal tissue of the placenta would be damaged, causing bleeding. The maternal and fetal blood would mix, causing an immune reaction. The umbilical vein would be blocked, preventing waste export from the fetus. The umbilical artery would be blocked, preventing oxygen import to the fetus.

Answer 1

The correct answer is The maternal and fetal blood would mix, causing an immune reaction.

Explanation:

In humans, the placental barrier made up of covering the villi, the trophoblastic epithelium, the fetal capillary endothelium, and the chorionic connective tissue. The placental barrier can act as a barrier between the fetus and the mother, preventing some harmful chemicals and substances present in the blood of the mother from damaging the fetus.

Mixing of the mother and fetus blood can cause an immune response to the fetus and damage it.

Thus, the correct answer is The maternal and fetal blood would mix, causing an immune reaction.

Answer 2

Basically, this chorion tissue is made of the chorionic villi and this functions by providing maximum contact area with the blood of the mother. So in case this tissue ruptures, what happens is that the maternal tissue of the placenta would be damaged and this may result in bleeding. Hope this helps.
