Study Notes
Placenta Development and Function
- The chorion facilitates nutrient and gas exchange between the maternal and fetal compartments.
- The fetal component of the placenta is derived from the trophoblast.
- The trophoblast is responsible for the erosion of maternal vessels to release blood into intervillous spaces in the placenta.
- The morula and blastula participate in the formation of the embryo but not in the formation of the placenta.
- The decidua is derived from the uterine endometrium in the placenta.
Test your knowledge on the extra-embryonic membranes and placenta, which play vital roles in prenatal development. Learn about the chorion, yolk sac, allantoic diverticulum, umbilical cord, and amnion, as well as the functions of the placenta in facilitating nutrient and gas exchange.
