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.
Arteries form part of the circulatory system. They carry blood that is oxygenated after it has been pumped from the heart. Arteries also aid the heart in pumping blood. Arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation.hile most arteries carry oxygenated blood, there are two exceptions to this, the pulmonary and the umbilical arteries. The effective arterial blood volume is that extracellular fluid which fills the arterial system. The circulatory system is vital for sustaining life.
