Fetal The flow of blood
When a baby is growing maternal blood supplies the o2, blood, and nutrients to the fetus and takes away the waste. The exchange of maternal bloodstream and embrionario blood towards the fetus takes place through the placental membrane and the umbilical power cord vessels. The umbilical line of thinking goes into your body through the umbilical ring, and half of the bloodstream running though it visits the liver and the snooze goes to the ductus venous. It ties with the second-rate vena cava. Blood goes to the fetal right innenhof from the substandard vena foso. From there, most blood experiences the foramen ovale in the left vorhof des herzens. The rest of the blood that makes its way into the right atrium comes from the superior filon cava, would go to the right ventricle, and out of your pulmonary trunk area. Since the lungs are collapsed only a very small amount would go to them. Blood from the second-rate vena give bypasses the lungs throughout the ductus arteriosus which connects to the climbing down part of the aortic arch. Bloodstream with low oxygen see the superior veta cava bypasses the lungs and does not proceed ingo fault the puls?re that goes for the heart and brain. The higher oxygen centered blood goes toward the left ventricle and it is pumped to the aorta exactly where some reaches the myocardium and some reaches the brain. When blood comes from the climbing down aorta it has the des oxygenated bloodstream from the ductus arteriosus. Some of that blood is taken to the lower areas of the body coming from branches from the aorta. The remaining blood goes thru the umbilical arteries. They will branch through the internal iliac arteries and lead to the placenta then your blood is re-oxygenated. The umbilical power cord has two arteries and one problematic vein.
