info_outlineWhat's the placenta? Some people think of it as a bag filled with fluid that protects the fetus inside from accidental blows, or a structure that sends maternal nutrients to the fetus while removing its waste products. Well, it's actually much more than this. When we may think that the placenta is protective, it can also create detrimental effects to the fetus - effects that can be lifelong. In fact, the placenta is a complex organ on its own and we've only recently been discovering some of the things that the placenta really does, and also what it can't do. Every new person that has arrived on this planet developed in a placenta, so to ensure the health and wellbeing of future generations, understanding what goes on with the placenta has become more critical. Today's guest is a leader in the field of placental biology. Dr. Cheryl Rosenfeld is professor of biomedical sciences and her cutting edge research on the multiple roles of the placenta and fetal development provides critical guidance for prenatal maternal lifestyle and care.
Key Takeaways:
- The placenta does have some ability to metabolize things, and it does offer some buffering capacity to the fetus.
- The placenta is an endocrine organ. It also produces neurotransmitters.
- Endocrine disrupters can be found in household items and everything around us. Understanding the green chemistry movement can help us lead a healthy life style.
"Even though we can't really, completely, eliminate our exposure to environmental chemicals. We can try to offset it by living with good healthy practices." — Dr. Cheryl Rosenfeld
