With a simple set of bolt-ons â like an intake, tune, and exhaust â we have no reservations that the EcoBoost will run with a GT, all while being able to achieve 32+ miles per gallon. Weâve seen Focus STâs pick up 30 horsepower and 50 lb/ft of torque to the wheels on just tunes.
The ductus arteriosus connects the pulmonary artery to the aorta, the ductus venosus connects the umbilical vein to the inferior vena cava, and the foramen ovale allows blood to go directly from the right atrium to the left atrium. The pathway of blood through the fetal circulation system is as follows:
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.
