Spleen
The skeletal system is what is responsible for calcium and phosphorous storage and hematopoiesis. Hematopoiesis is the production of blood cells.
No. The placenta produces and cleanses the blood for the fetus.
In case of the fetus, liver produces red blood cells. Red blood cells are produced by flat bones in case of adults. Given a challenge to produce the extra red blood cells, the liver may start producing red blood cells in adults also, as a last resort.

You can't test the mother's blood to determine the sex of the fetus, and blood testing wouldn't terribly effective in determining sex even if you're testing the blood of the fetus because most red cells, which make up the majority of cells in blood, have no nuclei. Amniocentesis is, however, extremely effective for this purpose.
A hemolytic disease of the newborn that is characterized by an increase in circulating red blood cells and by jaundice and that occurs when the system of an Rh-negative mother produces antibodies to an antigen in the blood of an Rh-positive fetus which cross the placenta and destroy fetal red blood cells, called also hemolytic disease of the newborn.
The placenta
no when Rh negative blood from the fetus interacts with Rh+ blood of the mother there will be no antibodies produced due to absence of antigen on the Rh- blood cells and when Rh positive is mixed with Rh negative blood of fetus no response is produced due to the fact that the fetus has an underdeveloped immune system
Bone marrow in an adult, bone marrow and spleen in an infant, spleen and liver in a fetus.
Oxygen gets from the air to the cells of the fetus through the umbilical cord. The oxygen circulates in the mothers red blood cells.
When the pig is a fetus in its mother uterus the liver contributes to the production of blood cells.
