Caption: Blood flow through the placenta. Colour doppler ultrasound scan showing blood flow through the human placenta in pregnancy. Here, communication of blood between two maternal veins on each side of the placenta is seen (yellow/red). The placenta links the blood supply of the mother with the developing foetus. This doppler ultrasound scan was made by Dr Philippe Saada. Saada obtains such high-definition images by linking ultrasound to a numeric colour video. Doppler ultrasound uses high-frequency sound waves to determine whether a pregnancy is normal, and can register moving particles like blood. Photographed at the Ultra- sound Centre of La Marjolaine at Montrouge, Paris.
