A. BARORECEPTORS CAUSE VASOCONSTRICTION AND INCREASE THE
FHR
If fetal arterial pressure begins to An increase in arterial blood pressure produces vessel
fall below normal levels: distension and causes arterial baroreceptors to send neuronal
messages to the cardioinhibitory center, which in turn causes
rapid slowing of the fetal heart rate via the parasympathetic vagus
nerve. A decrease in arterial pressure results in an increased
heart rate.

Which of the following is an Fetal-placental circulation

Fetal heart rate vaiability is AMPLITUDE and FREQUENCY

The most highly oxygenated Ductus venosus
blood in fetal circulation is
carried by:
Occlusion of the umbilical vein
The etiology of variable decelerations is likely related to umbilical venous

An increase in the fetal
arterial occlusion. Initially, with occlusion of the thin-walled
heart rate immediately
umbilical vein, venous return to the fetal right atrium is reduced,
preceding a variable
