The Placenta Anatomy Model is an anatomy model from 3B Scientific and manufactured in Germany. This anatomical model features the corrosion cast specimen of a human placenta embedded in crystal-clear plastic. The placenta includes detailed spatial portrayal of vessel arborisation and progression. The placenta villi is achieved by injecting different colored plastics in the placental vessels: red in the placental arteries and blue in the placental veins. The placenta specimens vary in shape as each is unique. This model is a great addition to a classroom or doctors office. The Placenta Anatomy Model is 8.3 x 6.7 x 1.6 in and weighs 3.31 lbs.
