Fetal chemoreceptors
WebFetal Circulation. The blood that flows through the fetus is actually more complicated than after the baby is born ( normal heart ). This is because the mother (the placenta) is doing the work that the baby’s lungs will do after birth. The placenta accepts the blood without oxygen from the fetus through blood vessels that leave the fetus ...

WebEarly in gestation the fetal heart rate is predominately under the control of the sympathetic nervous system and arterial chemoreceptors [1]. As the fetus develops its heart rate decreases in response to parasympathetic ( … WebStructural differences between fetal hemoglobin and adult hemoglobin make fetal hemoglobin unable to react with 2,3 diphophosphoglycerate (2,3-DPG) and thus to have a higher affinity for oxygen at a given partial pressure of oxygen. The fetal dissociation curve is thus shifted to the left relative to the adult curve. Typically, fetal arterial oxygen …
