The placenta is often taught as a temporary organ, but its role is anything but minor. This episode explores how the placenta and fetal membranes function as interfaces — exchanging gases, nutrients, hormones, and immune signals while maintaining separation.

IB Singh reinforces organisation and placental development timelines, and Moore anchors the discussion in clinical realities such as placental insufficiency, pre-eclampsia, and antenatal imaging. The placenta is presented as an adaptive organ, constantly responding to changing demands.

This episode highlights a recurring embryological theme: survival depends not just on growth, but on relationship.
