Abstract
Chorionic villi are the exchange structures of the placenta where human fetuses receive oxygen and nutrients from maternal blood, this article reports an improvement of a published method to recover them from the blood of pregnant, women, quotes their number and illustrates their size and trypsin impregnation. The reasons to explain the presence of chorionic structures and villi in the circulating maternal blood, the possible significance of their existence in maternal blood and the mechanisms to remove them are discussed. Their size and trypsin impregnation are illustrated. This paper discusses the significance of the presence of such allogeneic structures in the circulating blood of pregnant women and presents a brief discussion on the role of trypsin and its inhibitor in pregnancy homeostasis.
