The placenta is an organ that connects the developing fetus to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply. Placentae are a defining characteristic of eutherian or "placental" mammals, but are also found in some snakes and lizards with varying levels of development up to mammalian levels. The study was conducted in the Department of Anatomy, in Gauhati Medical College and Hospital. The material for the study, which consisted of 103 human placentae, was collected from the Labour Room of the Department of Obstetrics and Gynaecology of the same institution from a period between 01/06/2010 to 31/08/2011. Histological findings like hypermature villi, stromal fibrosis and syncytial knots are seen in higher range in eclampsia whereas decidual haematoma, obliterative endarteritis and fibrin deposition are more in preeclampsia cases. The average birth weight of baby is comparatively lower in hypertensive group but difference in weight in both control and study group is not statistically significant i.e. p> 0.05. A low ratio of weight of baby to weight of placenta is evident in pregnancy induced hypertension from the study. The relationship between both groups would have been more conclusive if more cases would have been available for study with detailed clinical correlation.
