During normal pregnancy, there is an exponential increase in cortisol concentrations in the fetalcirculation. As the placenta matures, the thickness of the trophoblastic epithelium decreases and this may lead to increased diffusion of drug molecules into the fetalcirculation. It readily crosses the placenta and enters the fetalcirculation and can be found in fetal tissues. Maternal hypertension may reduce placental blood -ow and transport capacity, and thus reduce transfer of nutrients to the fetalcirculation. Dramatic changes in the fetalcirculation occur in jeopardised fetuses and in particular venous waveform changes are indicative of fetal deterioration. The placenta links the uterus and the fetalcirculation, whereas the fetalcirculation and fetal brain are linked by the fetal blood brain barrier. This suggests that the placental vasculature can act as a large capacitor in the fetalcirculation. The possible mechanisms of intra-uterine transmission include transplacental infection and transfusion of maternal blood into the fetalcirculation. In addition, the fetalcirculation will affect drug transfer, so that an impaired fetalcirculation would reduce drug-transfer rates across the placenta.

The virus is then released from the placenta and reaches the fetalcirculation via the umbilical cord. The unique aspects of the fetalcirculation which have been reviewed hold important implications for circuitry. Noninvasive measurement of fetalcirculation using ultrasound: a new method. High concentrations of these cytokines in the fetalcirculation may thus indicate healthy placental function, which in turn may positively affect maturation of immune competence in the developing fetus. Transatrial flow, which represents a very important shunt in the fetalcirculation, seems also to be constant throughout pregnancy. Cardiac ultrasound was consistent with the clinical diagnosis of persistent fetalcirculation. These examples are from corpora and from sources on the web.
