False. The mothers blood flows through the placenta in vessels next to the foetal blood that flows in separate vessels. Oxygen and nutrients can flow from the mothers blood into the foetus' blood and carbon dioxide and waste products can flow from the foetus' blood to the mother's blood through the vessel membranes, however the two bloods will never actually mix.
