	This talk is intended to provide a broad introduction to placentation and its associated vascular development. This is such an interesting, and both clinically and diagnostically relevant topic in sonography.		This talk is intended to provide a broad introduction to placentation and its associated vascular development. This is such an interesting, and both clinically and diagnostically relevant topic in sonography.


	My talk will go through a time-course of development from earliest implantation through to the term placenta, specifically related to vascular development. Given that this process takes about 9 months, I will pick some key events in my 20 minute talk. I have designed this online resource for ongoing "self-directed" learning after the conference.
