The corrosion cast specimen of a human placenta is embedded in crystal-clear plastic.
Placenta has detailed spatial portrayal of vessel arborisation and progression. The placental 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. The placenta is a great addition to a classroom or doctors office.
