Foetal Circulation - Anatomy & Physiology

Foetal versus Adult Circulation

A large number of physiological processes that are necessary for the embryo’s survival, such as detoxification, gas exchange and waste removal, are carried out by the placenta rendering organs such as the liver and lungs surplus to requirement. There are a number of foetal circulatory shunts that ensure oxygen and nutrient rich blood flows directly to the most important organs, namely the brain, heart and adrenal glands.
