What is the purpose of the placenta?
Which part of the blastocyst eventually becomes the fetal placenta?
In birds, developing chicks rely on the yolk sac to provide essential nutrients, but in humans, this is not the case. Why don’t we need it to provide nutrition?
What is amniocentesis? How is it done?
Name the four extra-embryonic membranes.
