Elizabeth M. Ramsey and the evolution of ideas of uteroplacental blood flow and placental gas exchange.
During the past century a number of investigators have contributed to an understanding of the regulation of uteroplacental blood flow and its influence on placental respiratory gas exchange and fetal oxygenation. Among these, Elizabeth M. Ramsey is noteworthy for her contributions to embryology and placental development. In addition, with several colleagues she performed pioneering cineangiographic studies on the patterns of blood flow in the primate placenta.
