How do the placenta and umbilical cord suppost a growing embryo?
The placenta and umbilical cord play crucial roles in supporting a growing embryo by facilitating the exchange of nutrients, gases, and waste products between the mother and the developing fetus. The placenta, which forms from the outer layer of the embryo and the uterine lining, acts as an interface for this exchange, providing oxygen and essential nutrients while removing carbon dioxide and waste. The umbilical cord connects the fetus to the placenta, containing blood vessels that transport these materials, ensuring proper growth and development throughout pregnancy. Together, they create a vital connection that sustains the embryo until birth.
Where is the embryo gets it's nourishment?
After about a week from conception the zygote consists of over 100 cells. It then separates into two distinct mases. The outer cells form a shell that will become the placenta and the inner cells will become the embryo. First the outer cells must implant or embed themselves in the wall of the uterus. This occurs at about 10 days after conception. If implantation occurs the cells will grow and become an embryo and placenta. An umbilical cord forms and connects to the embryo's stomach and placenta so the embryo can get nourishment.
