How do human embryos obtain nutrients for growth and development before implantation in the endometrium?

∙ 11y ago
The embryoblast spends approximately 72 hours in the uterine cavity before implanting. in that time, it cannot receive nourishment directly from the blood of the mother, and must rely on secreted nutrients into the uterine cavity, e.g iron and fat-soluble vitamins.
