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:
Close to the inferior vena cava, it is found anterior to the aorta and inferior to the superior mesenteric artery. At the level of the T12, the right suprarenal vein drains into the inferior vena cava. The inferior phrenic veins drain into the posterolateral aspect of the inferior vena cava at the level of T10.
