Chief of the Reich Security Main Office (RSHA), Ernst Kaltenbrunner, went on trial at Nuremberg on April 11, 1946. He replaced Reinhard Heydrich who was assassinated by Czech agents in May, 1943 and assumed control over the SD and the Gestapo.
The placenta is connected to the fetus by an umbilical cord. Inside the cord are two arteries and a vein; both arteries are referred to as umbilical arteries. The two arteries wrap around the umbilical vein which carries oxygenated blood and nutrients from the placenta to the fetus. Once the oxygen and nutrients have been used, the umbilical artery transfers the deoxygenated blood and waste from the fetus back to the placenta.
This is because the mother (the placenta) is doing the work that the babyâs lungs will do after birth. The placenta accepts the bluest blood (blood without oxygen) from the fetus through blood vessels that leave the fetus through the umbilical cord (umbilical arteries, there are two of them).When blood goes through the placenta it picks up oxygen and becomes red.The red blood then returns to the fetus via the third vessel in the umbilical cord (umbilical vein). The red blood that enters the fetus passes through the fetal liver and enters the right side of the heart.he ductus arteriosus sends the bluer blood to the organs in the lower half of the fetal body. This also allows for the bluest blood to leave the fetus through the umbilical arteries and get back to the placenta to pick up oxygen.
