===Foetal 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 [[Female Reproductive Tract -Placenta - Anatomy & Physiology]] 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.
