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.
The pulmonary artery connects the lungs and the right ventricle of heart and is divided into left pulmonary artery and right pulmonary artery. The deoxygenated blood collected from the body is sent back to the heartâs right ventricle.urprisingly the function of pulmonary artery is absent in fetus. Because, when the fetus is attached to the mother through umbilical cord, he gets required oxygen from the mother and hence does not require lungs to provide him with it. This is the only situation when the function of pulmonary artery is absent.
