1 Electromagnetic coil, formed when a conductor is wound around a core or form to create an inductor or electromagnet.  Ignition coil, an electromagnetic induction coil used in internal combustion engines to create a pulse of high voltage for a spark plug.
systemic circulation the general circulation, carrying oxygenated blood from the left ventricle to the body tissues, and returning venous blood to the right atrium. umbilical circulation fetal circulation through the umbilical vessels. vitelline circulation the circulation through the blood vessels of the yolk sac.
The ductus arteriosus (DA) is also visible, between the pulmonary trunk (lower purple vessel with an arrow) and the aortic arch (upper purple vessel). Fetal liver circulation. The umbilical vein (UV) carries oxygenated blood from the placenta to the liver.Some of the blood mixes with blood in the hepatic portal vein (HPV) and enters the liver, but a significant minority passes through the ductus venosus (DV) which empties into the inferior vena cava (IVC) and carrys blood to the heart.etal circulation model. Look for: umbilical arteries and vein, ductus venosus, ductus arteriosus, foramen ovale. This model is best studied in lab, using the step by step circulation in the textbook or lab manual as a guide.
