Placental villi. Coloured scanning electron micrograph (SEM) of the villi (blue) of a placenta at full term. The villi,projections of foetal tissue into the maternal part of the placenta,together form a villous tree. Deoxygenated blood from the foetus flows through the villi and picks up oxygen and nutrients from the nearby maternal blood. Magnification: x230 at 5x7cm size. x800 at 9.5x6.5ins | |
