The Volume and Circulation of the Liquor Amnii [ Abridged ]

Abstract

The Anatomy of the Human Amnion and Chorion The anatomy, physiology and pathology of the foetal membranes have received insufficient attention and are, therefore, inadequately understood. A study of the anatomy reveals that these organs are complex and possess a structure which appears to be capable of transmitting fluid and materials between the fretus and the mother. The presence of a circulation between the amniotic fluid and the fcetus is now accepted. The exact volume of fluid exchanged is subject to controversy. In theory at least, a large amount of the fluid-exchange between the foetus and the mother should occur directly across the faotal membranes.
