The placenta performs all the functions needed for healthy growth and development of the baby. It also plays an important role in mediating maternal adaptations to pregnancy. It is amazing that all of these functions can be done by a single organ! Click on the link to learn more about the functions of the placenta.

The placenta is made up of functional units called chorionic villi. Click on the link to learn more about chorionic villi.


Blood flow through the placenta is an interesting and unique process. Click on the link to learn more about the blood flow.


An important aspect of placental development is the remodeling of the maternal uterine spiral arteries. Unremodeled spiral arteries lead reduced blood flow into the placenta. Click on the link to learn more about spiral arteries.


There are several methods used for placenta imaging. Click on the link to learn about Doppler Ultrasound, Magnetic Resonance Imaging (MRI) and Micro-focus Computed Tomography (Micro-CT).


We use a variety of techniques to study the placenta. Studying the placenta in healthy and complicated pregnancies is important to understand why problems arise and identify ways to prevent and treat them.
