, MD, Saint Louis University Class of Medicine

Monthly, an egg is released from an ovary into a tube that is fallopian. After sexual activity, sperm move through the vagina through the cervix and womb to your fallopian pipes, where one semen fertilizes the egg. The fertilized egg (zygote) divides over repeatedly because it moves along the tube that is fallopian the uterus. First, the zygote turns into a ball that is solid of. Then it becomes a ball that is hollow of called a blastocyst.

The blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes inside the uterus.

At 2 months of being pregnant, the placenta and fetus have now been developing for 6 days. The placenta kinds tiny projections that are hairlike) that increase to the wall surface associated with womb. Bloodstream through the embryo, which move across the cord that is umbilical the placenta, develop into the villi.

A slim membrane layer separates the embryo’s bloodstream within the villi through the mom’s blood that flows through the area surrounding the villi (intervillous area). The following is done by this arrangement:

Allows materials to be exchanged involving the blood associated with mom and therefore for the embryo
