placenta
The chorionic membrane is a thin, outermost membrane that surrounds the fetus in the womb. It is composed of layers of cells derived from both the embryo and the mother and plays a role in the exchange of nutrients and waste between the fetus and the mother. The chorionic membrane eventually fuses with the amniotic membrane to form the amniotic sac.
The chorion is the outer membrane surrounding the embryo that is continuous with the placenta, the highly vascular structure that acts as a physical communication between the mother and the embryo.

The uterine membrane, comprised of the placenta, facilitates the exchange of nutrients, oxygen, and waste products between the mother and embryo. This transport occurs through diffusion, active transport, and facilitated diffusion mechanisms. The placenta also acts as a barrier to prevent harmful substances from crossing between the maternal and fetal circulations.
The placenta is the organ responsible for passing materials between the mother and developing embryo during pregnancy. It acts as a barrier to protect the fetus from infections and helps in the exchange of oxygen, nutrients, and waste products between the mother and the developing baby.
In a haplodiploid system, mother and daughter are closely related because daughters inherit all their genetic material from their mother. This results in a higher genetic relatedness between mother and daughter compared to other systems.
An embryo shares half of the genetic pattern of the mother. HOWEVER- you said HOST mother. In the case of a fertilized egg implanted in a mother that did NOT donate the egg, then there is no genetic relation between embryo and host mother.
it is the interface between the fetus and the mother's blood supply it acts like a filter - supplying nutrients to the fetus and disposing of waste material from the fetus to the mother all of this without actually mixing the blood of the fetus and the mother
The mother picks them up by the scruff of there neck and transports them to another place... don't worry, it doesn't hurt them! :)
