The transfer of oxygen from mother to fetus is also favoured by the presence of fetal haemoglobin which shifts the fetal oxyhaemoglobin dissociation curve further to the left. Smokers placenta have shown a highly significant increase in number and size of syncytial buds when compared with normal placenta. but the complete conversion of one tissue into another does not take place. The exchange of nutrients between placenta and fetus involves three major mechanisms (1) direct placental transfer of nutrients from the maternal to the fetal plasma; (2) placental metabolism and consumption of nutrients; (3) placental metabolism of nutrient substrates to alternate substrate forms. . the ET-1 immunoreactivity in placenta of active smokers was consistently observed to be more intense as compared to non-smokers' placenta.

Within the placenta, oxygen and nutrient delivery and carbon dioxide and waste removal are facilitated by the intervillous space between placental and uterine tissue. At a given oxygen tension, the quantity of oxygen carried by blood depends on the oxygen capacity (which is dependent on the hemoglobin concentration) and the oxygen affinity. Oxygen, carbon dioxide, and any other lipid-soluble substances take this route. . Oxygen, carbon dioxide, and any other lipid-soluble substances take this route. Oxygen and nutrients from the mother&x27;s blood are transferred across the placenta to the fetus through the umbilical cord. 1 a) is achieved as fetal blood circulates from the umbilical arteries to the capillaries inside the placental villi and returns to the umbilical vein, whereas maternal blood percolates through a relatively high-volume intervillous compartment outside this arboreous structure.
