If the placenta were to detach from mothers uterus early would embryo stop receiving food and oxygen?

If the placenta were to detach from the mother's uterus early, the embryo would indeed stop receiving food and oxygen.

- Food-supply: The placenta allows nutrients to pass from the mother's circulatory system to the embryo's developing bloodstream.

- Exchange of respiratory gases: Placenta enables the gaseous exchange of carbon dioxide and oxygen between maternal and fetal circulation. Fetal oxygen supply depends completely upon diffusion into the microcirculation of the villi from oxygenated maternal blood.
