The Fetus and Neonate is a series of practical, focused texts which concentrate on that critical period of human development, from late fetal to neonatal life. Each volume in the series examines a particular body system, looking at the physiological mechanisms which underlie the transition from intrauterine to extrauterine life, and the pathophysiological processes which may occur in this period. Each volume will consider the application of new basic scientific knowledge to the clinical situation. This series will be a valuable source of information to practitioners and postgraduate trainees in obstetrics, neonatology, paediatrics and reproductive medicine, as well as to basic scientists in these fields.

The placenta is an organ that connects the developing fetus to the uterine wall, thereby allowing nutrient uptake, waste elimination, and gas exchange via the mother's blood supply. Proper vascular development in the placenta is fundamental to ensuring a healthy fetus and successful pregnancy. This book provides an up-to-date summary and synthesis of knowledge regarding placental vascular biology and discusses the relevance of this vascular bed to the functions of the human placenta.

The Hepatic circulation is unique among vascular beds. The most obvious unique features include the dual vascular supply; the mechanism of intrinsic regulation of the hepatic artery (the hepatic arterial buffer response); the fact that portal blood flow, supplying two thirds of liver blood flow, is not controlled directly by the liver; the fact that 20% of the cardiac output rushes through the most vascularized organ in the body, driven by a pressure gradient of only a few millimeters of mercury; the extremely distensible capacitance and venous resistance sites; the unidirectional acinar blood flow that regulates parenchymal cell metabolic specialization; and the high concentration of macrophagic (Kupffer) cells filtering the blood. The liver is the only organ reported to have regional blood flow monitored by the autonomic nervous system. This mechanism, when dysfunctional, accounts for the hepatorenal syndrome and offers a mechanistic therapeutic target to treat this syndrome. The trigger for liver regeneration is dependent on hepatic hemodynamics so that chronic liver blood flow regulates liver cell mass. In severe liver disease, the whole body circulation is reorganized, by forming portacaval shunts, to accommodate the increased intrahepatic venous resistance. These shunts protect the venous drainage of the splanchnic organs but lead to loss of major regulatory roles of the liver. The development of knowledge of the hepatic vasculature is presented from a historical perspective with modern concepts summarized based on the perspective of the author's four decades of devotion to this most marvelous of organs.

Biology of Gestation Volume II provides an account of the various mechanisms that take place during the adjustment of the fetus to intrauterine life and the changes that happen at birth. The book covers topics such as the growth and composition of the newborn and the fetus, fetal and neonatal circulation, and maternal and fetal blood constituents. Also covered are topics such as the lung and kidneys, and the development of the nervous system and immunologic function of neonates and the fetus. The text is recommended for biologists and doctors, especially gynecologists and pediatricians, who would like to know more about the anatomy and biological processes of fetuses and neonates.
